Key Facts

Overview

11088 (1993 UN) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1993 UN as potentially hazardous because its orbit does not bring it close to Earth.

1993 UN orbits the sun every 1,160 days (3.18 years), coming as close as 1.82 AU and reaching as far as 2.51 AU from the sun. 1993 UN is about 3.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

The rotation of 1993 UN has been observed. It completes a rotation on its axis every 58.52 hours.

No Close Approaches

1993 UN's orbit is 0.81 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

1993 UN's orbit is determined by observations dating back to Oct. 9, 1993. It was last officially observed on Feb. 19, 2023. The IAU Minor Planet Center records 2,291 observations used to determine its orbit.

Accessibility and Exploration

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