Key Facts

Overview

103501 (2000 AT245) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 2000 AT245 as potentially hazardous because its orbit does not bring it close to Earth.

2000 AT245 orbits the sun every 1,250 days (3.42 years), coming as close as 1.63 AU and reaching as far as 2.93 AU from the sun. Based on its brightness and the way it reflects light, 2000 AT245 is probably between 2.242 to 5.012 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

The rotation of 2000 AT245 has been observed. It completes a rotation on its axis every 29.95 hours.

No Close Approaches

2000 AT245's orbit is 0.77 AU from Earth's orbit at its closest point. This means that there is a very 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

2000 AT245's orbit is determined by observations dating back to Oct. 12, 1998. It was last officially observed on Jan. 18, 2023. The IAU Minor Planet Center records 2,099 observations used to determine its orbit.

Accessibility and Exploration

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