Antinous is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Antinous 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.
Antinous orbits the sun every 1,240 days (3.39 years), coming as close as 0.89 AU and reaching as far as 3.63 AU from the sun. Antinous is about 2.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.
The rotation of Antinous has been observed. It completes a rotation on its axis every 7.45 hours.
Antinous's spectral type SU (Tholen) / Sq (SMASSII) indicates that it is likely to contain and .
Antinous's orbit is 0.18 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.
Antinous has 1 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Aug. 13, 2094||28,891,840||18.044|
Antinous's orbit is determined by observations dating back to March 5, 1948. It was last officially observed on Dec. 1, 2022. The IAU Minor Planet Center records 1,098 observations used to determine its orbit.
