Key Facts

Overview

10565 (1994 AT1) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1994 AT1 as potentially hazardous because its orbit does not bring it close to Earth.

1994 AT1 orbits the sun every 1,580 days (4.33 years), coming as close as 2.05 AU and reaching as far as 3.26 AU from the sun. 1994 AT1 is about 13.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

The rotation of 1994 AT1 has been observed. It completes a rotation on its axis every 14.45 hours.

No Close Approaches

1994 AT1's orbit is 1.06 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

1994 AT1's orbit is determined by observations dating back to Feb. 18, 1933. It was last officially observed on Dec. 13, 2022. The IAU Minor Planet Center records 6,470 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
