Key Facts

Overview

505624 (2014 GU53) is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2014 GU53 as potentially hazardous because its orbit does not bring it close to Earth.

2014 GU53 orbits the sun every 106,000 days (290.21 years), coming as close as 36.10 AU and reaching as far as 51.50 AU from the sun. Based on its brightness and the way it reflects light, 2014 GU53 is probably between 192.555 to 430.566 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Maryland.

No Close Approaches

2014 GU53's orbit is 35.20 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

2014 GU53's orbit is determined by observations dating back to May 14, 2010. It was last officially observed on July 13, 2020. The IAU Minor Planet Center records 322 observations used to determine its orbit.

Accessibility and Exploration

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