  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

51365 (2000 TA42) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2000 TA42 as potentially hazardous because its orbit does not bring it close to Earth.

2000 TA42 orbits the sun every 4,350 days (11.91 years), coming as close as 4.92 AU and reaching as far as 5.51 AU from the sun. 2000 TA42 is about 40.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of 2000 TA42 has been observed. It completes a rotation on its axis every 58.76 hours.

No Close Approaches

2000 TA42's orbit is 4.03 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

2000 TA42's orbit is determined by observations dating back to Nov. 4, 1989. It was last officially observed on July 1, 2023. The IAU Minor Planet Center records 2,329 observations used to determine its orbit.

Accessibility and Exploration

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