Key Facts

Overview

2000 GL147 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2000 GL147 as potentially hazardous because its orbit does not bring it close to Earth.

2000 GL147 orbits the sun every 90,100 days (246.68 years), coming as close as 31.39 AU and reaching as far as 47.27 AU from the sun. Based on its brightness and the way it reflects light, 2000 GL147 is probably between 44.112 to 98.637 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Rhode Island.

No Close Approaches

2000 GL147's orbit is 30.40 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

2000 GL147's orbit is determined by observations dating back to April 2, 2000. It was last officially observed on April 7, 2000. The IAU Minor Planet Center records 3 observations used to determine its orbit.

Accessibility and Exploration

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