Famous asteroids predicted to hit Earth
News about an asteroid heading to Earth with a chance of impact arouses great interest. In fact, as of February 2025, there are 2,467 potentially dangerous asteroids, but only a handful make headlines. Let’s discuss the most famous asteroids coming to Earth in the near future and see if any of them pose a threat to our planet.
April 13, 2029: Apophis
Apophis is a large near-Earth asteroid, approximately 370 meters (1213 feet) in diameter (about the size of the Empire State Building). It orbits the Sun about every 324 days.
The asteroid will come close to our planet in 2029, 2036, and 2068. Initial calculations suggested a potential collision with Earth in 2029. However, subsequent observations have confirmed that Apophis will not collide with our planet for at least the next 100 years. Read our article to learn all the details about the asteroid Apophis.
December 22, 2032: 2024 YR4 ☄️
Asteroid 2024 YR4 was discovered by the ATLAS telescope on December 27, 2024. At approximately 44-100 meters in diameter, it is comparable in size to a high building (15-30 stories). The asteroid completes an orbit around the Sun roughly every 4 years. Shortly after its discovery, astronomers realized that it had already passed close to Earth on December 25, 2024, at a distance of 830,000 kilometers (about 2.15 times the distance to the Moon).
Will asteroid 2024 YR4 hit Earth?
As of January 2025, asteroid 2024 YR4 has six identified impact probabilities, with the nearest occurring on December 22, 2032. The likelihood of the asteroid hitting Earth on that date is currently estimated to be 1 in 35. An asteroid with a risk this high hasn’t been seen in nearly 20 years! Now, asteroid 2024 YR4 has astronomers on high alert. Could it strike Earth in 2032, and what damage would it cause? Discover everything you need to know.
February 14, 2046: 2023 DW
Asteroid 2023 DW was discovered on February 26, 2023. According to NASA, it is about 50 meters (160 feet) in diameter, which is roughly as wide as an American football field. It is moving at a speed of 25 km/s (15.5 m/s) and completes one orbit around the Sun in 271 days.
Back in February 2023, the asteroid was predicted to have a chance of colliding with the Earth on February 14, 2046. It was added to the ESA’s Risk List (a catalog of objects that can probably hit the Earth) and rated 1 on the Torino scale (the other 1,450 asteroids on the list had a scale ranking of 0). However, as early as mid-March 2023, ESA lowered the rating to 0 and then removed it from the list. NASA did the same: 2023 DW is now on the list of objects for which “all previously detected potential impacts have been eliminated”. So it looks like we're lucky, and asteroid 2023 DW won't hit Earth.
Where to learn the latest news on asteroids heading for Earth?
You can easily check if any asteroid gets close to our planet soon. Open the Minor Planet Center’s website and find the Close Approaches list in the lower-right part of the main page. It contains all the known asteroids that will pass by Earth within a close range in the next few months. Apart from the asteroid’s name and date of close approach, you can learn its size (in meters) and the distance at which it will fly past the Earth (in lunar distances).
NASA's Asteroid Watch Dashboard provides similar information, but with visual references, which make it easier to imagine the size of the asteroid. Note that it only displays the 5 upcoming approaches.
If you’re interested in a particular asteroid, use NASA JPL’s Small-Body Database Browser. Enter the asteroid’s name or number, and you will get extensive information on its orbit, physical parameters, and discovery circumstances.
You can track the position of an asteroid in the sky using the Sky Tonight app. Tap the magnifier icon and type its name in the search bar. When the asteroid appears in the search results, tap the blue target icon next to its name. Sky Tonight will show you the asteroid’s current location in the sky.
What are the chances of an asteroid hitting Earth?
From astronomers' point of view, collisions between celestial bodies are normal. And you might find it surprising that they occur pretty frequently. Small asteroids (around 1m in diameter) hit the Earth every two weeks; as you can see, nothing special happens.
However, a big asteroid may cause a worldwide catastrophe: tons of dust and ash will rise to the sky and block the Sun for several years. Crop failures and forest fires will begin, leading to mass famine. The good thing is, according to NASA, asteroids larger than 100 meters that can cause local damage hit the Earth about every 10,000 years. Space rocks larger than 1 kilometer that can threaten life on our planet come along only once in a few million years. In other words, there’s a very small chance you’ll be harmed by an asteroid over your lifetime. Despite that, it’s always good to be prepared. Let’s take a look at the measures astronomers take to guarantee the Earth’s safety.
How do we tell dangerous asteroids from non-dangerous ones?
More than 1 million asteroids have been discovered, and not every one of them is worth worrying about. Scientists pay special attention to the so-called potentially hazardous asteroids. To be classified as potentially hazardous, an asteroid must meet two main criteria.
-
First, it must have a minimum orbit intersection distance (MOID) with Earth of 0.05 AU or less. An asteroid with such an orbit can get dangerously close to our planet.
-
Second, it must have an absolute magnitude of 22.0 or less. The smallest asteroids of such brightness are estimated to be 110 to 240 meters in size – it is enough to cause significant local damage in case of impact.
An asteroid’s hazard potential is measured using two scales: the Torino Impact Hazard Scale and the Palermo Technical Impact Hazard Scale. The Torino scale is used to communicate the potential risk of a future asteroid impact to the general public. On this simple scale, an object is assigned a 0 to 10 value based on its collision probability and the kinetic energy of the possible collision. The Palermo scale is a similar but more complex scale that is mainly used by professional astronomers.
The orbits of celestial bodies are changing under the influence of the gravity of the Sun, planets, and other asteroids. Therefore, as soon as an asteroid is labeled as potentially dangerous, scientists keep track of it and perform high-precision calculations. If an asteroid is observed for ten years, its orbit can be calculated 200 years ahead.
What size asteroid is dangerous?
As we’ve said before, not every asteroid impact can lead to disaster. So, how big of an asteroid can cause serious damage? To answer this question, let’s turn to examples.
- The Chicxulub impactor that caused mass extinction on Earth 65 million years ago was about 10 kilometers in diameter. This very asteroid presumably ended the age of the dinosaurs.
- The Tunguska impactor that exploded in the air and flattened 80 million trees of the taiga forest in 1908 was about 100 meters in diameter. This was and still is the largest asteroid impact in recorded history.
- Finally, the Chelyabinsk meteor that entered Earth’s atmosphere in 2013 was about 20 meters in diameter. This asteroid didn’t even reach the terrestrial surface, but its explosion still damaged more than 7,000 buildings. To learn more about these three famous asteroids, watch our video.
You can make a conclusion yourself. Even comparatively small space rocks, like the Chelyabinsk meteor, can cause local damage. Asteroids larger than 1 kilometer can have worldwide effects like causing long-term climate change. For a better visual understanding, see our infographic in which we compared the size of asteroids with the possible consequences of the impact.
How many potentially hazardous asteroids are there?
As of February 2025, astronomers have detected 2,467 potentially hazardous asteroids, of which 152 are larger than 1 kilometer (0.6 miles) in diameter. The largest known potentially hazardous asteroid is (53319) 1999 JM8 – it is estimated to be about 7 kilometers in diameter.
We’d like to emphasize that this data doesn’t mean that all of these asteroids will eventually hit Earth – only that they have the potential to do so. None of these asteroids pose any sufficient risk of impact within the next 100 years. You can find more particular info on the NASA CNEOS website. There’s a table there that summarizes all the potential future impact events and provides hazard ratings using the Torino and Palermo scales.
How do we spot near-Earth asteroids?
Over the past 30 years, we’ve made significant progress in discovering near-Earth asteroids: astronomers report new ones almost daily. Many projects constantly work on detecting near-Earth objects (NEOs) – asteroids and comets that pass close to Earth’s orbit. Let’s name just a few of such projects.
-
First, there’s ATLAS – the Asteroid Terrestrial-impact Last Alert System built in Hawaii. It consists of two 0.5-meter telescopes located 160 km apart that survey the sky every clear night. Among other NEOs, ATLAS discovered the famous comet C/2019 Y4 (ATLAS).
-
Then, there’s Catalina Sky Survey (CSS) located in the Catalina Mountains, Arizona, USA. This astronomical survey focuses specifically on detecting potentially hazardous asteroids and estimating impact risks.
-
Apart from ground-based telescopes, there’s also a space telescope working on the Earth’s orbit. It’s called the Near-Earth Object Wide-field Infrared Survey Explorer or NEOWISE. Currently, NEOWISE is searching for asteroids that could potentially collide with Earth. Among its many discoveries, there’s the naked-eye comet C/2020 F3 (NEOWISE).
In the past ten years, ground-based surveys and NASA’s space telescope have detected thousands of near-Earth objects and greatly contributed to our knowledge about tracking asteroids and comets. According to recent data, more than 90% of near-Earth asteroids larger than 1 km in diameter (large enough to have global consequences) have been discovered already. However, about half of the small asteroids are only found when they have already passed the Earth. Sometimes astronomers notice an asteroid just a few days before its approach to the Earth, as happened with the asteroid 2024 XA1 that blazed over Siberia in December 2024. Currently, it’s the best that we can do.
How can we stop asteroids from hitting Earth?
So, what can we do if there’s an asteroid headed for Earth? Scientists are working on ways to defend the planet. The good news is we have a number of possible solutions, and at least one of them has already been tested successfully. The not-very-good news is we can’t unfold any of them in an instant. A typical space mission of such sort takes several years from approval to launch. This means we must detect dangerous asteroids years (better, a decade) before they come close to Earth if we want to make a spacecraft to deflect them in time. That’s why it’s so important to find as many near-Earth objects as possible and calculate their orbits in advance. Here are some of the ideas on how to avoid the impact that we have at the moment.
DART
The Double Asteroid Redirection Test (DART) was NASA's mission that tested the technologies for preventing an asteroid impact. The target of the mission was asteroid Dimorphos – the moonlet of the binary near-Earth asteroid Didymos. In September 2022, the DART spacecraft crashed into the moonlet (which is about 160 m in size), thus changing its speed and orbital period. This mission proved that a hazardous space rock could be deflected in the future.
Gravity tractor
This method employs a spacecraft that would accompany an asteroid for several years and use its gravitational attraction to pull the rock off course slowly. Gravity tractors can work with asteroids of any shape and composition. They are highly controllable, which makes it possible to ensure an asteroid will be placed into a safe orbit. However, they might be unable to pull the largest asteroids (over 500 meters in diameter), which pose the greatest threat to the Earth.
Spray painting
When it comes to deflecting asteroids, painting is different from what you immediately think of. However, the idea is based on a real-world phenomenon known as the Yarkovsky effect, which describes how sunlight affects an asteroid's orbit. In short, darker surfaces tend to reflect less, and lighter surfaces tend to reflect more. By changing the amount of light an asteroid gives off, we could change its path. The method lacks precision and would take years or even decades to show any remarkable effect. On the other hand, if something goes wrong, scientists will have enough time to recalculate and try again.
Nuclear weapon
A nuclear bomb could be a last-minute choice when an asteroid is just about to hit the Earth, and there would be no time left to deploy other options. The idea is to blow up a nuclear explosive at the proper distance from an asteroid (not on its surface) to push it off its current path. The pros are that the mission can be conducted relatively fast using already-existing technologies (we could arm a rocket with a nuclear warhead and launch it from a conventional launch pad). The cons are that an asteroid may shatter into pieces, which could cause even more damage.
Is Jupiter protecting Earth from being hit by an asteroid?
The idea that Jupiter protects Earth from asteroids is a topic of ongoing scientific debate, and the answer is both yes and no, depending on the context.
-
On one hand, as the largest planet in the Solar System, Jupiter has an immense gravitational field. This allows it to act as a “cosmic vacuum cleaner,” pulling in or deflecting asteroids, comets, and other debris that might otherwise cross Earth's orbit. Many objects from the outer Solar System are diverted or captured by Jupiter before they can threaten Earth. A good example of this is comet Shoemaker-Levy 9, which crashed into Jupiter in 1994 instead of continuing through the Solar System. Also, Jupiter plays a crucial role in maintaining the structure of the asteroid belt, a region located between Mars and Jupiter that contains the majority of known asteroids. Its powerful gravitational pull counteracts the Sun's influence, helping to stabilize the orbits of asteroids (at least most of the time).
-
On the other hand, simulations suggest that while Jupiter is effective at deflecting long-period comets from the Oort Cloud, it can also attract short-period comets and asteroids toward Earth. Under the influence of Jupiter’s gravity, these objects – ones that might not have otherwise come near us – can be nudged into new orbits that increase their chances of impacting the terrestrial planets.
In summary, Jupiter's immense size and gravitational influence help reduce the frequency of asteroid impacts on Earth. However, its role is not purely that of a shield: it can occasionally direct objects toward us. So, the best defense we have is ourselves.

To sum up: will an asteroid hit Earth in 2025?
Definitely! Give it two weeks or less. Tiny asteroids hit Earth all the time, but they’re so small they barely make a dent. Bigger asteroids could bring bigger problems, but this year, all of them are expected to swoosh by Earth with no risk of impact. For now, there is nothing to worry about, so you can just track the brightest asteroids via Sky Tonight and observe them without fear that they will hit the Earth.
