2009 SD93

Key Facts

• Categorized as a Outer Main-belt Asteroid
• Comparable in size to the U.S. Pentagon
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

2009 SD93 is a mid-sized asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 2009 SD93 as potentially hazardous because its orbit does not bring it close to Earth.

2009 SD93 orbits the sun every 3,260 days (8.93 years), coming as close as 2.20 AU and reaching as far as 6.40 AU from the sun. Based on its brightness and the way it reflects light, 2009 SD93 is probably between 0.884 to 1.977 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.

No Close Approaches

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

Images and Observations

2009 SD93's orbit is determined by observations dating back to Sept. 19, 2009. It was last officially observed on Sept. 20, 2009. The IAU Minor Planet Center records 15 observations used to determine its orbit.

Accessibility and Exploration

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