Key Facts

Overview

Oersted is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified Oersted as potentially hazardous because its orbit does not bring it close to Earth.

Oersted orbits the sun every 2,120 days (5.80 years), coming as close as 3.05 AU and reaching as far as 3.41 AU from the sun. Oersted is about 22.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

No Close Approaches

Oersted's orbit is 2.05 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

Oersted's orbit is determined by observations dating back to March 22, 1955. It was last officially observed on March 9, 2023. The IAU Minor Planet Center records 3,375 observations used to determine its orbit.

Accessibility and Exploration

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