Key Facts


13429 (1999 VM35) is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 1999 VM35 as potentially hazardous because its orbit does not bring it close to Earth.

1999 VM35 orbits the sun every 2,340 days (6.41 years), coming as close as 3.21 AU and reaching as far as 3.68 AU from the sun. 1999 VM35 is about 12.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

The rotation of 1999 VM35 has been observed. It completes a rotation on its axis every 81.37 hours.

No Close Approaches

1999 VM35's orbit is 2.21 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

1999 VM35's orbit is determined by observations dating back to Nov. 30, 1986. It was last officially observed on July 6, 2022. The IAU Minor Planet Center records 2,261 observations used to determine its orbit.
