Key Facts
- Categorized as a Inner Main-belt Asteroid
- Comparable in size to the island of Manhattan (3.99 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Priestley is a mid-sized asteroid orbiting between Mars and Jupiter within the inner portion of the asteroid belt. NASA JPL has not classified Priestley as potentially hazardous because its orbit does not bring it close to Earth.
Priestley orbits the sun every 915 days (2.51 years), coming as close as 1.76 AU and reaching as far as 1.93 AU from the sun. Priestley is about 4.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.
The rotation of Priestley has been observed. It completes a rotation on its axis every 160.00 hours.
No Close Approaches
Priestley's orbit is 0.77 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
Priestley's orbit is determined by observations dating back to Nov. 16, 1976. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 3,506 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
