What are the names of the asteroids that cross Earth's orbit and Jupiter's orbit?

Answer 1

1. Main Belt asteroids -- a band of asteroids located in the "missing planet" gap between Mars and Jupiter. None of these are economically attractive in a near term program because they are too far from Earth.
2. Amor asteroids -- asteroids whose orbits approach but do not cross Earth orbit, and whose orbits are further from the Sun than Earth's orbit (i.e., "outside-t" Earth orbit). Many have orbits which reside entirely between Earth and Mars. Some of these are economically attractive in the near term.
3. Apollo asteroids -- asteroids whose orbits cross Earth's orbit. Apollo asteroids spend most of their time outside Earth orbit. Many of these are economically attractive in the near term.
4. Aten asteroids -- asteroids whose orbits cross Earth's orbit. Unlike Apollos, Atens spend most of their time inside Earth orbit. A large percentage of known Atens are economically attractive in the near term.
