Key Facts

  • Categorized as a Asteroid
  • Comparable in size to the Golden Gate Bridge
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

2012 DO45 is a small asteroid whose orbit does not match any defined asteroid orbital class. NASA JPL has not classified 2012 DO45 as potentially hazardous because its orbit does not bring it close to Earth.

2012 DO45 orbits the sun every 3,950 days (10.81 years), coming as close as 1.40 AU and reaching as far as 8.38 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2012 DO45 is probably between 0.497 to 1.112 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

No Close Approaches

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

Images and Observations

2012 DO45's orbit is determined by observations dating back to Feb. 26, 2012. It was last officially observed on Feb. 29, 2012. The IAU Minor Planet Center records 10 observations used to determine its orbit.

Accessibility and Exploration

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