Key Facts

Overview

36269 (1999 XB214) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1999 XB214 as potentially hazardous because its orbit does not bring it close to Earth.

1999 XB214 orbits the sun every 4,370 days (11.96 years), coming as close as 4.89 AU and reaching as far as 5.57 AU from the sun. Based on its brightness and the way it reflects light, 1999 XB214 is probably between 12.094 to 27.042 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Philadelphia.

The rotation of 1999 XB214 has been observed. It completes a rotation on its axis every 6.78 hours.

No Close Approaches

1999 XB214's orbit is 3.93 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 XB214's orbit is determined by observations dating back to Dec. 19, 1998. It was last officially observed on March 2, 2023. The IAU Minor Planet Center records 1,509 observations used to determine its orbit.

Accessibility and Exploration

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