Halawe

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the city of Philadelphia (16.16 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Halawe orbits the sun every 1,470 days (4.02 years), coming as close as 1.96 AU and reaching as far as 3.11 AU from the sun. Halawe is about 16.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.

The rotation of Halawe has been observed. It completes a rotation on its axis every 14.31 hours.

No Close Approaches

Halawe's orbit is 0.96 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

Halawe's orbit is determined by observations dating back to Oct. 20, 1903. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 7,506 observations used to determine its orbit.
