NASA Ambition Of Our Planet

Last year NASA discovered an asteroid that orbits the Earth. It orbits the sun and circles the Earth too so it is a satellite. This asteroid will be orbiting the Earth for centuries. This asteroid that orbits the Earth is called HO3. In the asteroid’s trip around the sun it spends half its orbit closer to the sun than Earth, it also passes ahead of our planet, and about half of its orbit farther away. It is too distant to be a true satellite of our planet, but it is the best and most stable example to date of a near-Earth companion, or "quasi-satellite."
