Aristaeus is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Aristaeus as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
Aristaeus orbits the sun every 739 days (2.02 years), coming as close as 0.80 AU and reaching as far as 2.40 AU from the sun. Based on its brightness and the way it reflects light, Aristaeus is probably between 0.699 to 1.563 kilometers in diameter, making it small in absolute terms, but larger than ~97% of asteroids, very roughly comparable in size to the Golden Gate Bridge.
Aristaeus's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
Aristaeus has 5 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|March 26, 2062||12,697,449||15.967|
|April 2, 2064||8,172,764||18.760|
|March 19, 2145||26,244,415||14.529|
|March 30, 2147||4,447,586||17.026|
|April 6, 2149||14,373,099||19.684|
Aristaeus's orbit is determined by observations dating back to April 17, 1977. It was last officially observed on June 9, 2018. The IAU Minor Planet Center records 58 observations used to determine its orbit.
