Home The main asteroid belt lies between Mars and Jupiter, whereas Trojan asteroids both lead and follow Jupiter. Scientists now know that asteroids in the early solar system (4.6 billion years ago) adhered together and eventually formed the inner planets, including Earth. (NASA/ESA/J.

NASA’s Hubble Space Telescope snapped this image of the young comet P/2019 LD2 as it orbits near Jupiter’s captured ancient asteroids, which are called Trojans. The Hubble view reveals a 400,000-mile-long tail of dust and gas flowing from the wayward comet’s bright solid nucleus. (NASA/ESA/J. Olmsted/STScI)
