Key Facts

Overview

1996 RQ20 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1996 RQ20 as potentially hazardous because its orbit does not bring it close to Earth.

1996 RQ20 orbits the sun every 106,000 days (290.21 years), coming as close as 39.37 AU and reaching as far as 48.21 AU from the sun. Based on its brightness and the way it reflects light, 1996 RQ20 is probably between 110.804 to 247.765 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Connecticut.

No Close Approaches

1996 RQ20's orbit is 38.40 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

1996 RQ20's orbit is determined by observations dating back to Sept. 6, 1996. It was last officially observed on Oct. 7, 2013. The IAU Minor Planet Center records 52 observations used to determine its orbit.

Accessibility and Exploration

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