Key Facts

Overview

32906 (1994 RH) is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1994 RH as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

1994 RH orbits the sun every 1,230 days (3.37 years), coming as close as 1.26 AU and reaching as far as 3.24 AU from the sun. Based on its brightness and the way it reflects light, 1994 RH is probably between 1.646 to 3.682 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

The rotation of 1994 RH has been observed. It completes a rotation on its axis every 2.64 hours.

1994 RH's spectral type None (Tholen) / S (SMASSII) indicates that it is likely to contain and .

No Close Approaches

1994 RH's orbit is 0.45 AU from Earth's orbit at its closest point. This means that there is a 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 RH's orbit is determined by observations dating back to Sept. 21, 1984. It was last officially observed on May 2, 2022. The IAU Minor Planet Center records 2,656 observations used to determine its orbit.

Accessibility and Exploration

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