Key Facts

Overview

11435 (1931 UB) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1931 UB as potentially hazardous because its orbit does not bring it close to Earth.

1931 UB orbits the sun every 1,380 days (3.78 years), coming as close as 1.90 AU and reaching as far as 2.95 AU from the sun. 1931 UB is about 4.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

No Close Approaches

1931 UB's orbit is 0.90 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

1931 UB's orbit is determined by observations dating back to Oct. 17, 1931. It was last officially observed on Feb. 19, 2023. The IAU Minor Planet Center records 2,906 observations used to determine its orbit.

Accessibility and Exploration

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