Overview

5590 (1990 VA) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 1990 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.

1990 VA orbits the sun every 357 days (0.98 years), coming as close as 0.71 AU and reaching as far as 1.26 AU from the sun. Based on its brightness and the way it reflects light, 1990 VA is probably between 0.305 to 0.682 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

1990 VA's orbit is 0.12 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.

1990 VA has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Oct. 6, 2033 26,923,623 13.848
Oct. 6, 2034 18,315,258 10.987
Oct. 14, 2035 22,496,841 9.452
Oct. 5, 2080 24,333,981 13.280
Oct. 7, 2081 17,915,929 10.769

Images and Observations

1990 VA's orbit is determined by observations dating back to Nov. 9, 1990. It was last officially observed on Dec. 5, 1996. The IAU Minor Planet Center records 67 observations used to determine its orbit.
