Key Facts

Overview

2005 GY206 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2005 GY206 as potentially hazardous because its orbit does not bring it close to Earth.

2005 GY206 orbits the sun every 91,400 days (250.24 years), coming as close as 34.78 AU and reaching as far as 44.64 AU from the sun. Based on its brightness and the way it reflects light, 2005 GY206 is probably between 75.955 to 169.840 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.

No Close Approaches

2005 GY206's orbit is 33.80 AU from Earth's orbit at its closest point. This means that there is an extremely 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

2005 GY206's orbit is determined by observations dating back to April 11, 2005. It was last officially observed on April 12, 2005. The IAU Minor Planet Center records 4 observations used to determine its orbit.

Accessibility and Exploration

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