- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Sundmania is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Sundmania as potentially hazardous because its orbit does not bring it close to Earth.
Sundmania orbits the sun every 2,080 days (5.69 years), coming as close as 3.01 AU and reaching as far as 3.37 AU from the sun. Sundmania is about 64.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.
The rotation of Sundmania has been observed. It completes a rotation on its axis every 93.73 hours.
Sundmania's spectral type None (Tholen) / X (SMASSII) indicates that it is likely to contain iron, nickel, and cobalt.
No Close Approaches
Sundmania's orbit is 2.02 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
Sundmania's orbit is determined by observations dating back to Nov. 22, 1918. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 4,802 observations used to determine its orbit.
