Key Facts

Overview

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

Petaev orbits the sun every 1,380 days (3.78 years), coming as close as 1.83 AU and reaching as far as 3.03 AU from the sun. Petaev is about 10.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.

No Close Approaches

Petaev's orbit is 0.83 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

Petaev's orbit is determined by observations dating back to Sept. 23, 1949. It was last officially observed on May 30, 2023. The IAU Minor Planet Center records 2,364 observations used to determine its orbit.

Accessibility and Exploration

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