Key Facts

Overview

6279 (1977 UO5) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1977 UO5 as potentially hazardous because its orbit does not bring it close to Earth.

1977 UO5 orbits the sun every 2,030 days (5.56 years), coming as close as 2.55 AU and reaching as far as 3.71 AU from the sun. 1977 UO5 is about 16.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.

The rotation of 1977 UO5 has been observed. It completes a rotation on its axis every 9.96 hours.

No Close Approaches

1977 UO5's orbit is 1.57 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

1977 UO5's orbit is determined by observations dating back to Dec. 9, 1950. It was last officially observed on June 10, 2023. The IAU Minor Planet Center records 3,016 observations used to determine its orbit.

Accessibility and Exploration

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