Key Facts
- Categorized as a Inner Main-belt Asteroid
- Comparable in size to Mount Everest (2.55 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Hickson is a mid-sized asteroid orbiting between Mars and Jupiter within the inner portion of the asteroid belt. NASA JPL has not classified Hickson as potentially hazardous because its orbit does not bring it close to Earth.
Hickson orbits the sun every 976 days (2.67 years), coming as close as 1.82 AU and reaching as far as 2.03 AU from the sun. Hickson is about 2.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.
The rotation of Hickson has been observed. It completes a rotation on its axis every 23.80 hours.
No Close Approaches
Hickson's orbit is 0.86 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
Hickson's orbit is determined by observations dating back to Sept. 24, 1990. It was last officially observed on Jan. 29, 2023. The IAU Minor Planet Center records 2,353 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
