Arabis

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the city of Houston (37.50 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Arabis orbits the sun every 1,910 days (5.23 years), coming as close as 2.75 AU and reaching as far as 3.28 AU from the sun. Arabis is about 37.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Houston.

The rotation of Arabis has been observed. It completes a rotation on its axis every 5.79 hours.

No Close Approaches

Arabis's orbit is 1.76 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

Arabis's orbit is determined by observations dating back to Sept. 2, 1927. It was last officially observed on April 21, 2023. The IAU Minor Planet Center records 3,605 observations used to determine its orbit.
