Overview

100004 (1983 VA) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1983 VA 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.

1983 VA orbits the sun every 1,520 days (4.16 years), coming as close as 0.77 AU and reaching as far as 4.41 AU from the sun. Its orbit is highly elliptical. 1983 VA is about 2.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

The rotation of 1983 VA has been observed. It completes a rotation on its axis every 3.16 hours.

Close Approaches

1983 VA's orbit is 0.17 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.

1983 VA has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Nov. 15, 2063 22,615,755 16.523
Nov. 21, 2084 28,628,705 16.865
