Astraea is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Astraea as potentially hazardous because its orbit does not bring it close to Earth.
Astraea orbits the sun every 1,510 days (4.13 years), coming as close as 2.08 AU and reaching as far as 3.07 AU from the sun. Astraea is about 106.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.
The rotation of Astraea has been observed. It completes a rotation on its axis every 16.81 days.
Astraea's orbit is 1.10 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.
Astraea's orbit is determined by observations dating back to Dec. 15, 1845. It was last officially observed on April 26, 2020. The IAU Minor Planet Center records 3,034 observations used to determine its orbit.
Scientists have been able to determine this object's shape.
