Overview

620092 (2015 HB10) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2015 HB10 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2015 HB10 orbits the sun every 922 days (2.52 years), coming as close as 0.79 AU and reaching as far as 2.91 AU from the sun. Based on its brightness and the way it reflects light, 2015 HB10 is probably between 0.555 to 1.242 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2015 HB10's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

2015 HB10 has 12 close approaches predicted in the coming decades:
