Key Facts

Overview

433200 (2012 UM51) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 2012 UM51 as potentially hazardous because its orbit does not bring it close to Earth.

2012 UM51 orbits the sun every 1,720 days (4.71 years), coming as close as 2.43 AU and reaching as far as 3.19 AU from the sun. Based on its brightness and the way it reflects light, 2012 UM51 is probably between 1.357 to 3.034 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

No Close Approaches

2012 UM51's orbit is 1.45 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

2012 UM51's orbit is determined by observations dating back to May 16, 2001. It was last officially observed on Nov. 26, 2022. The IAU Minor Planet Center records 217 observations used to determine its orbit.

Accessibility and Exploration

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