Key Facts

Overview

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

Frieda orbits the sun every 1,170 days (3.20 years), coming as close as 1.86 AU and reaching as far as 2.49 AU from the sun. Frieda is about 8.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Frieda has been observed. It completes a rotation on its axis every 131.10 hours.

No Close Approaches

Frieda's orbit is 0.85 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

Frieda's orbit is determined by observations dating back to March 9, 1910. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 10,938 observations used to determine its orbit.

Accessibility and Exploration

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