Small Bodies

According to the International Astronomical Union, small Solar System bodies include comets, asteroids, and trans-Neptunian objects (except for dwarf planets). Most asteroids and trans-Neptunian objects are located in the asteroid belt and the Kuiper Belt. The comets mainly come from the Oort Cloud. From time to time, small Solar System bodies can get quite close to the Earth and even become potentially hazardous objects. Here, you'll learn many interesting facts about different types of small bodies and discover which of them are really to be feared.
