Key Facts

Overview

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

Campai orbits the sun every 1,670 days (4.57 years), coming as close as 2.70 AU and reaching as far as 2.82 AU from the sun. Based on its brightness and the way it reflects light, Campai is probably between 5.502 to 12.304 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

The rotation of Campai has been observed. It completes a rotation on its axis every 314.25 hours.

No Close Approaches

Campai's orbit is 1.69 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

Campai's orbit is determined by observations dating back to July 21, 1977. It was last officially observed on July 1, 2023. The IAU Minor Planet Center records 2,879 observations used to determine its orbit.

Accessibility and Exploration

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