Key Facts

Overview

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

Fetisov orbits the sun every 1,720 days (4.71 years), coming as close as 2.43 AU and reaching as far as 3.18 AU from the sun. Based on its brightness and the way it reflects light, Fetisov is probably between 5.528 to 12.361 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

No Close Approaches

Fetisov's orbit is 1.45 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

Fetisov's orbit is determined by observations dating back to Sept. 28, 1976. It was last officially observed on June 25, 2023. The IAU Minor Planet Center records 2,646 observations used to determine its orbit.

Accessibility and Exploration

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