Overview

2021 VH1 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2021 VH1 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.

2021 VH1 orbits the sun every 221 days (0.61 years), coming as close as 0.43 AU and reaching as far as 1.00 AU from the sun. Based on its brightness and the way it reflects light, 2021 VH1 is probably between 0.014 to 0.031 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2021 VH1's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2021 VH1 has 11 close approaches predicted in the coming decades:
