Wenpingchen

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the San Francisco Bay
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Wenpingchen orbits the sun every 1,790 days (4.90 years), coming as close as 2.72 AU and reaching as far as 3.06 AU from the sun. Based on its brightness and the way it reflects light, Wenpingchen is probably between 3.842 to 8.591 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

No Close Approaches

Wenpingchen's orbit is 1.70 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

Wenpingchen's orbit is determined by observations dating back to Oct. 14, 1990. It was last officially observed on June 24, 2023. The IAU Minor Planet Center records 2,289 observations used to determine its orbit.

Accessibility and Exploration

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