Key Facts

Overview

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

Cari orbits the sun every 1,620 days (4.44 years), coming as close as 2.14 AU and reaching as far as 3.26 AU from the sun. Cari is about 11.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.

No Close Approaches

Cari's orbit is 1.14 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

Cari's orbit is determined by observations dating back to May 27, 1993. It was last officially observed on June 9, 2023. The IAU Minor Planet Center records 2,659 observations used to determine its orbit.

Accessibility and Exploration

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