Overview

152756 (1999 JV3) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1999 JV3 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.

1999 JV3 orbits the sun every 638 days (1.75 years), coming as close as 0.85 AU and reaching as far as 2.05 AU from the sun. Based on its brightness and the way it reflects light, 1999 JV3 is probably between 0.423 to 0.946 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

The rotation of 1999 JV3 has been observed. It completes a rotation on its axis every 2.85 hours.

1999 JV3's spectral type None (Tholen) / S (SMASSII) indicates that it is likely to contain and .

Close Approaches

1999 JV3's orbit is 0.07 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.

1999 JV3 has 13 close approaches predicted in the coming decades:
