Overview

85990 (1999 JV6) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1999 JV6 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

1999 JV6 orbits the sun every 370 days (1.01 years), coming as close as 0.69 AU and reaching as far as 1.32 AU from the sun. 1999 JV6 is about 0.5 kilometers in diameter, making it small in absolute terms, but larger than 90% of asteroids, comparable in size to the U.S. Capitol building.

The rotation of 1999 JV6 has been observed. It completes a rotation on its axis every 6.54 days.

1999 JV6's spectral type None (Tholen) / Xk (SMASSII) indicates that it is likely to contain nickel, iron, and cobalt.

Close Approaches

1999 JV6's orbit is 0.03 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.

1999 JV6 has 22 close approaches predicted in the coming decades:
