Key Facts

Overview

103276 (2000 AT33) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 2000 AT33 as potentially hazardous because its orbit does not bring it close to Earth.

2000 AT33 orbits the sun every 1,140 days (3.12 years), coming as close as 1.55 AU and reaching as far as 2.72 AU from the sun. Based on its brightness and the way it reflects light, 2000 AT33 is probably between 1.108 to 2.478 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.

No Close Approaches

2000 AT33's orbit is 0.56 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 AT33's orbit is determined by observations dating back to Dec. 12, 1996. It was last officially observed on June 20, 2023. The IAU Minor Planet Center records 610 observations used to determine its orbit.

Accessibility and Exploration

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