Key Facts

Overview

13856 (1999 XZ105) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1999 XZ105 as potentially hazardous because its orbit does not bring it close to Earth.

1999 XZ105 orbits the sun every 1,600 days (4.38 years), coming as close as 2.17 AU and reaching as far as 3.17 AU from the sun. 1999 XZ105 is about 14.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

The rotation of 1999 XZ105 has been observed. It completes a rotation on its axis every 4.45 hours.

No Close Approaches

1999 XZ105's orbit is 1.19 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.
