Key Facts
- Categorized as a Main-belt Asteroid
- Comparable in size to the San Francisco Bay (4.86 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Gunn is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Gunn as potentially hazardous because its orbit does not bring it close to Earth.
Gunn orbits the sun every 1,230 days (3.37 years), coming as close as 2.03 AU and reaching as far as 2.45 AU from the sun. Gunn is about 4.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
The rotation of Gunn has been observed. It completes a rotation on its axis every 6.64 hours.
No Close Approaches
Gunn'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.
Images and Observations
Gunn's orbit is determined by observations dating back to Sept. 25, 1973. It was last officially observed on July 3, 2023. The IAU Minor Planet Center records 4,055 observations used to determine its orbit.
Accessibility and Exploration
This asteroid is not considered a viable target for human exploration by the NHATS study.Similar Objects
