Overview

Quetzalcoatl is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Quetzalcoatl 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.

Quetzalcoatl orbits the sun every 1,482 days (4.06 years), coming as close as 1.09 AU and reaching as far as 3.99 AU from the sun. Quetzalcoatl is about 0.5 kilometers in diameter, making it a small to average asteroid, comparable in size to the Golden Gate Bridge.

The rotation of Quetzalcoatl has been observed. It completes a rotation on its axis every 4.90 days.

Close Approaches

Quetzalcoatl's orbit is 0.11 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.

Quetzalcoatl has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Feb. 24, 2062 20,038,040 13.015
Feb. 25, 2114 11,653,569 14.085
March 14, 2153 15,147,654 16.126

Images and Observations

Quetzalcoatl's orbit is determined by observations dating back to March 9, 1953. It was last officially observed on Oct. 9, 2004. The IAU Minor Planet Center records 51 observations used to determine its orbit.

Accessibility and Exploration

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