162192 (1999 RY28)

Key Facts

• Categorized as a Mars-crossing Asteroid
• Comparable in size to the U.S. Pentagon
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

162192 (1999 RY28) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 1999 RY28 as potentially hazardous because its orbit does not bring it close to Earth.

1999 RY28 orbits the sun every 962 days (2.63 years), coming as close as 1.61 AU and reaching as far as 2.20 AU from the sun. Based on its brightness and the way it reflects light, 1999 RY28 is probably between 1.103 to 2.466 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.

No Close Approaches

1999 RY28's orbit is 0.68 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

1999 RY28's orbit is determined by observations dating back to July 22, 1999. It was last officially observed on June 30, 2023. The IAU Minor Planet Center records 998 observations used to determine its orbit.

Accessibility and Exploration

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