Key Facts
- Categorized as a Main-belt Asteroid
- Comparable in size to the San Francisco Bay (5.50 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Ingalls is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Ingalls as potentially hazardous because its orbit does not bring it close to Earth.
Ingalls orbits the sun every 1,230 days (3.37 years), coming as close as 1.84 AU and reaching as far as 2.65 AU from the sun. Ingalls is about 5.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
The rotation of Ingalls has been observed. It completes a rotation on its axis every 3.78 hours.
No Close Approaches
Ingalls's orbit is 0.83 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
Ingalls's orbit is determined by observations dating back to May 21, 1931. It was last officially observed on Feb. 2, 2023. The IAU Minor Planet Center records 3,555 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
