Key Facts

Overview

138359 (2000 GX127) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 GX127 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.

2000 GX127 orbits the sun every 445 days (1.22 years), coming as close as 0.73 AU and reaching as far as 1.55 AU from the sun. 2000 GX127 is about 1.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the Golden Gate Bridge.

The rotation of 2000 GX127 has been observed. It completes a rotation on its axis every 3.69 hours.

No Close Approaches

2000 GX127's orbit is 0.26 AU from Earth's orbit at its closest point. This means that there is a 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 GX127's orbit is determined by observations dating back to April 10, 2000. It was last officially observed on May 31, 2022. The IAU Minor Planet Center records 587 observations used to determine its orbit.

Accessibility and Exploration

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