Key Facts
- Categorized as a Main-belt Asteroid
- Comparable in size to the U.S. state of Rhode Island (58.29 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Angelina is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Angelina as potentially hazardous because its orbit does not bring it close to Earth.
Angelina orbits the sun every 1,600 days (4.38 years), coming as close as 2.34 AU and reaching as far as 3.02 AU from the sun. Angelina is about 58.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.
The rotation of Angelina has been observed. It completes a rotation on its axis every 8.75 hours.
Angelina's spectral type E (Tholen) / Xe (SMASSII) indicates that it is likely to contain iron, nickel, and cobalt.
No Close Approaches
Angelina's orbit is 1.36 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
Angelina's orbit is determined by observations dating back to March 8, 1861. It was last officially observed on June 8, 2023. The IAU Minor Planet Center records 5,239 observations used to determine its orbit.
