Overview

2009 HV58 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2009 HV58 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2009 HV58 orbits the sun every 1,020 days (2.79 years), coming as close as 0.83 AU and reaching as far as 3.14 AU from the sun. Based on its brightness and the way it reflects light, 2009 HV58 is probably between 0.302 to 0.676 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

2009 HV58'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.

2009 HV58 has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Dec. 2, 2022 4,719,530 28.842
Nov. 25, 2036 18,170,281 30.669
Dec. 7, 2117 17,121,023 27.882
Dec. 1, 2131 7,282,275 29.469
Nov. 22, 2145 28,984,207 31.909
