Key Facts
- Categorized as a Inner Main-belt Asteroid
- Comparable in size to the San Francisco Bay (5.64 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Farmer is a mid-sized asteroid orbiting between Mars and Jupiter within the inner portion of the asteroid belt. NASA JPL has not classified Farmer as potentially hazardous because its orbit does not bring it close to Earth.
Farmer orbits the sun every 1,010 days (2.77 years), coming as close as 1.86 AU and reaching as far as 2.07 AU from the sun. Farmer is about 5.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
The rotation of Farmer has been observed. It completes a rotation on its axis every 250.00 hours.
No Close Approaches
Farmer's orbit is 0.85 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
Farmer's orbit is determined by observations dating back to Dec. 4, 1989. It was last officially observed on April 17, 2023. The IAU Minor Planet Center records 3,291 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
