Spacewatch is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified Spacewatch as potentially hazardous because its orbit does not bring it close to Earth.
Spacewatch orbits the sun every 2,900 days (7.94 years), coming as close as 3.39 AU and reaching as far as 4.57 AU from the sun. Spacewatch is about 15.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Baltimore.
The rotation of Spacewatch has been observed. It completes a rotation on its axis every 20.00 hours.
Spacewatch's orbit is 2.37 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.
Spacewatch's orbit is determined by observations dating back to Feb. 11, 1977. It was last officially observed on Jan. 12, 2023. The IAU Minor Planet Center records 1,409 observations used to determine its orbit.
