Do we know if there are asteroids leading or following Earth in Earth's orbit around the Sun?
There are several known Earth co-orbital asteroids. The first to be discovered was (3753) Cruithne, which is often mistakenly described as &quot;Earth's second moon&quot;. Cruithne has a bean-shaped orbit when viewed in a reference frame rotating with the Earth.
The only known Earth Trojan is 2010 TK7, which orbits the L4 point located 60° ahead of the Earth.
