147997 (1996 RH26)

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

147997 (1996 RH26) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 1996 RH26 as potentially hazardous because its orbit does not bring it close to Earth.

1996 RH26 orbits the sun every 1,130 days (3.09 years), coming as close as 1.64 AU and reaching as far as 2.61 AU from the sun. Based on its brightness and the way it reflects light, 1996 RH26 is probably between 1.144 to 2.559 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.

No Close Approaches

1996 RH26's orbit is 0.63 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

1996 RH26's orbit is determined by observations dating back to Oct. 9, 1993. It was last officially observed on April 15, 2023. The IAU Minor Planet Center records 651 observations used to determine its orbit.

Accessibility and Exploration

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