- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Agnia is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Agnia as potentially hazardous because its orbit does not bring it close to Earth.
Agnia orbits the sun every 1,690 days (4.63 years), coming as close as 2.52 AU and reaching as far as 3.05 AU from the sun. Agnia is about 24.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.
The rotation of Agnia has been observed. It completes a rotation on its axis every 14.83 hours.
Agnia's spectral type S (Tholen) / S (SMASSII) indicates that it is likely to contain and .
No Close Approaches
Agnia's orbit is 1.53 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
Agnia's orbit is determined by observations dating back to Oct. 8, 1906. It was last officially observed on Feb. 19, 2023. The IAU Minor Planet Center records 4,091 observations used to determine its orbit.
