Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the San Francisco Bay (9.76 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

8402 (1994 GH9) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1994 GH9 as potentially hazardous because its orbit does not bring it close to Earth.

1994 GH9 orbits the sun every 1,550 days (4.24 years), coming as close as 2.01 AU and reaching as far as 3.23 AU from the sun. 1994 GH9 is about 9.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of 1994 GH9 has been observed. It completes a rotation on its axis every 13.54 hours.

No Close Approaches

1994 GH9's orbit is 1.04 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.
