Aten is a mid-sized asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified Aten 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.
Aten orbits the sun every 347 days (0.95 years), coming as close as 0.79 AU and reaching as far as 1.14 AU from the sun. Aten is about 1.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the Golden Gate Bridge.
The rotation of Aten has been observed. It completes a rotation on its axis every 40.77 days.
Aten's orbit is 0.11 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.
Aten has 13 close approaches predicted in the coming decades:
