Key Facts

Overview

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

Chepurova orbits the sun every 1,320 days (3.61 years), coming as close as 2.01 AU and reaching as far as 2.70 AU from the sun. Chepurova is about 9.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Chepurova has been observed. It completes a rotation on its axis every 145.74 hours.

No Close Approaches

Chepurova's orbit is 1.01 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

Chepurova's orbit is determined by observations dating back to June 30, 1954. It was last officially observed on June 23, 2023. The IAU Minor Planet Center records 3,639 observations used to determine its orbit.

Accessibility and Exploration

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