Key Facts

Overview

136568 (1980 XB) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 1980 XB as potentially hazardous because its orbit does not bring it close to Earth.

1980 XB orbits the sun every 1,390 days (3.81 years), coming as close as 1.54 AU and reaching as far as 3.34 AU from the sun. 1980 XB is about 2.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

The rotation of 1980 XB has been observed. It completes a rotation on its axis every 2.78 hours.

No Close Approaches

1980 XB's orbit is 0.61 AU from Earth's orbit at its closest point. This means that there is a very 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

1980 XB's orbit is determined by observations dating back to Dec. 13, 1980. It was last officially observed on July 1, 2023. The IAU Minor Planet Center records 1,795 observations used to determine its orbit.

Accessibility and Exploration

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