Key Facts

Overview

147057 (2002 RY106) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 2002 RY106 as potentially hazardous because its orbit does not bring it close to Earth.

2002 RY106 orbits the sun every 1,280 days (3.50 years), coming as close as 1.66 AU and reaching as far as 2.96 AU from the sun. Based on its brightness and the way it reflects light, 2002 RY106 is probably between 2.007 to 4.488 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

The rotation of 2002 RY106 has been observed. It completes a rotation on its axis every 2.68 hours.

No Close Approaches

2002 RY106's orbit is 0.66 AU from Earth's orbit at its closest point. This means that there is a very 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

2002 RY106's orbit is determined by observations dating back to Feb. 4, 2000. It was last officially observed on May 26, 2022. The IAU Minor Planet Center records 881 observations used to determine its orbit.

Accessibility and Exploration

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