  • See orbit simulation

Overview

2010 RF12 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 RF12 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2010 RF12 orbits the sun every 399 days (1.09 years), coming as close as 0.86 AU and reaching as far as 1.26 AU from the sun. Based on its brightness and the way it reflects light, 2010 RF12 is probably between 0.004 to 0.016 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2010 RF12's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.

2010 RF12 has 14 close approaches predicted in the coming decades:

Images and Observations

2010 RF12's orbit is determined by observations dating back to Sept. 3, 2010. It was last officially observed on Sept. 8, 2010. The IAU Minor Planet Center records 323 observations used to determine its orbit.

Accessibility and Exploration

2010 RF12 can be reached with a journey of 450 days. This trajectory would require a delta-v of 5.921 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 572,221 potential trajectories and launch windows to this asteroid.
