Key Facts
- Categorized as a Mars-crossing Asteroid
- Comparable in size to the island of Manhattan (3.00 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Chetaev is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified Chetaev as potentially hazardous because its orbit does not bring it close to Earth.
Chetaev orbits the sun every 1,200 days (3.29 years), coming as close as 1.62 AU and reaching as far as 2.80 AU from the sun. Chetaev is about 3.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.
The rotation of Chetaev has been observed. It completes a rotation on its axis every 102.00 hours.
No Close Approaches
Chetaev's orbit is 0.60 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
Chetaev's orbit is determined by observations dating back to Aug. 8, 1978. It was last officially observed on June 9, 2023. The IAU Minor Planet Center records 2,688 observations used to determine its orbit.
Accessibility and Exploration
This asteroid is not considered a viable target for human exploration by the NHATS study.Similar Objects
