Overview

162723 (2000 VM2) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 VM2 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.

2000 VM2 orbits the sun every 864 days (2.36 years), coming as close as 0.57 AU and reaching as far as 2.98 AU from the sun. Based on its brightness and the way it reflects light, 2000 VM2 is probably between 0.803 to 1.795 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2000 VM2's orbit is 0.11 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.

2000 VM2 has 7 close approaches predicted in the coming decades:
