Key Facts

Overview

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

Fram orbits the sun every 1,690 days (4.63 years), coming as close as 2.55 AU and reaching as far as 3.01 AU from the sun. Fram is about 12.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

Fram's spectral type None (Tholen) / C (SMASSII) indicates that it is likely to contain water, iron, nickel, cobalt, nitrogen, and ammonia.

No Close Approaches

Fram's orbit is 1.56 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

Fram's orbit is determined by observations dating back to Sept. 25, 1984. It was last officially observed on May 7, 2023. The IAU Minor Planet Center records 2,824 observations used to determine its orbit.

Accessibility and Exploration

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