Key Facts

Overview

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

Kressida orbits the sun every 1,260 days (3.45 years), coming as close as 1.86 AU and reaching as far as 2.70 AU from the sun. Kressida is about 14.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

The rotation of Kressida has been observed. It completes a rotation on its axis every 11.93 hours.

No Close Approaches

Kressida's orbit is 0.88 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

Kressida's orbit is determined by observations dating back to Oct. 15, 1904. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 6,673 observations used to determine its orbit.

Accessibility and Exploration

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