Key Facts

Overview

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

Obermair orbits the sun every 1,370 days (3.75 years), coming as close as 2.19 AU and reaching as far as 2.65 AU from the sun. Based on its brightness and the way it reflects light, Obermair is probably between 2.242 to 5.012 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

No Close Approaches

Obermair's orbit is 1.19 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

Obermair's orbit is determined by observations dating back to July 24, 1979. It was last officially observed on June 5, 2023. The IAU Minor Planet Center records 1,844 observations used to determine its orbit.

Accessibility and Exploration

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