Summanus is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Summanus 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.
Summanus orbits the sun every 812 days (2.22 years), coming as close as 0.90 AU and reaching as far as 2.51 AU from the sun. Summanus is about 1.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. Pentagon.
The rotation of Summanus has been observed. It completes a rotation on its axis every 7.37 hours.
Summanus's orbit is 0.07 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.
Summanus has 5 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|March 20, 2031||22,078,897||17.472|
|March 1, 2120||29,864,471||11.493|
|March 5, 2140||21,658,182||12.281|
|March 6, 2160||19,992,280||12.458|
|March 4, 2180||23,498,976||12.099|
Summanus's orbit is determined by observations dating back to Sept. 25, 1990. It was last officially observed on Sept. 15, 2021. The IAU Minor Planet Center records 352 observations used to determine its orbit.
