24806 (1994 RH9)

Key Facts

• Categorized as a Mars-crossing Asteroid
• Comparable in size to the island of Manhattan
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

24806 (1994 RH9) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 1994 RH9 as potentially hazardous because its orbit does not bring it close to Earth.

1994 RH9 orbits the sun every 1,370 days (3.75 years), coming as close as 1.57 AU and reaching as far as 3.25 AU from the sun. Based on its brightness and the way it reflects light, 1994 RH9 is probably between 2.646 to 5.916 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

No Close Approaches

1994 RH9's orbit is 0.57 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

1994 RH9's orbit is determined by observations dating back to June 3, 1975. It was last officially observed on June 9, 2023. The IAU Minor Planet Center records 1,379 observations used to determine its orbit.

Accessibility and Exploration

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