Key Facts

  • Categorized as a Jupiter Trojan
  • Comparable in size to the city of Indianapolis (26.20 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

20995 (1985 VY) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1985 VY as potentially hazardous because its orbit does not bring it close to Earth.

1985 VY orbits the sun every 4,200 days (11.50 years), coming as close as 4.51 AU and reaching as far as 5.69 AU from the sun. 1985 VY is about 26.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

The rotation of 1985 VY has been observed. It completes a rotation on its axis every 10.47 hours.

No Close Approaches

1985 VY's orbit is 3.52 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

1985 VY's orbit is determined by observations dating back to Nov. 1, 1985. It was last officially observed on Jan. 22, 2023. The IAU Minor Planet Center records 1,347 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
