Overview

2018 HV1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 HV1 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2018 HV1 orbits the sun every 584 days (1.60 years), coming as close as 0.68 AU and reaching as far as 2.05 AU from the sun. Based on its brightness and the way it reflects light, 2018 HV1 is probably between 0.064 to 0.143 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2018 HV1's orbit is 0.05 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.

2018 HV1 has 14 close approaches predicted in the coming decades:
