Key Facts

Overview

37572 (1989 UC5) is a mid-sized asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1989 UC5 as potentially hazardous because its orbit does not bring it close to Earth.

1989 UC5 orbits the sun every 4,360 days (11.94 years), coming as close as 4.46 AU and reaching as far as 5.98 AU from the sun. Based on its brightness and the way it reflects light, 1989 UC5 is probably between 5.709 to 12.766 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

No Close Approaches

1989 UC5's orbit is 3.46 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

1989 UC5's orbit is determined by observations dating back to Oct. 18, 1977. It was last officially observed on Aug. 21, 2022. The IAU Minor Planet Center records 422 observations used to determine its orbit.

Accessibility and Exploration

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