Apollo is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Apollo as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
Apollo orbits the sun every 651 days (1.78 years), coming as close as 0.65 AU and reaching as far as 2.29 AU from the sun. Apollo is about 1.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. Pentagon.
The rotation of Apollo has been observed. It completes a rotation on its axis every 3.07 days.
Apollo's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
Apollo has 13 close approaches predicted in the coming decades:
