Chengyuhsuan

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to Mount Everest
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Chengyuhsuan orbits the sun every 1,280 days (3.50 years), coming as close as 2.10 AU and reaching as far as 2.50 AU from the sun. Based on its brightness and the way it reflects light, Chengyuhsuan is probably between 1.917 to 4.286 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

No Close Approaches

Chengyuhsuan's orbit is 1.11 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

Chengyuhsuan's orbit is determined by observations dating back to Oct. 2, 1996. It was last officially observed on June 19, 2023. The IAU Minor Planet Center records 1,578 observations used to determine its orbit.

Accessibility and Exploration

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