Anza is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Anza as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
Anza orbits the sun every 1,240 days (3.39 years), coming as close as 1.05 AU and reaching as far as 3.48 AU from the sun. Anza is about 2.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.
The rotation of Anza has been observed. It completes a rotation on its axis every 11.50 days.
Anza's orbit is 0.06 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
Anza has 5 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Sept. 27, 2035||8,031,333||6.660|
|Aug. 27, 2093||26,837,692||10.561|
|Oct. 11, 2110||10,135,596||7.279|
|Sept. 12, 2151||13,930,713||7.728|
|Oct. 27, 2168||26,187,829||10.746|
Anza's orbit is determined by observations dating back to Oct. 22, 1960. It was last officially observed on Feb. 17, 2020. The IAU Minor Planet Center records 922 observations used to determine its orbit.
