Overview

2011 GD60 is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2011 GD60 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.

2011 GD60 orbits the sun every 412 days (1.13 years), coming as close as 0.91 AU and reaching as far as 1.26 AU from the sun. Based on its brightness and the way it reflects light, 2011 GD60 is probably between 0.800 to 3.560 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

Close Approaches

2011 GD60's orbit is 0.06 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2011 GD60 has 23 close approaches predicted in the coming decades:

Images and Observations

2011 GD60's orbit is determined by observations dating back to April 8, 2011. It was last officially observed on April 19, 2020. The IAU Minor Planet Center records 154 observations used to determine its orbit.

Accessibility and Exploration

2011 GD60 can be reached with a journey of 362 days. This trajectory would require a delta-v of 7.911 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 60,954 potential trajectories and launch windows to this asteroid.
