Key Facts
- Categorized as a Main-belt Asteroid
- Comparable in size to the island of Manhattan (4.12 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Richard is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Richard as potentially hazardous because its orbit does not bring it close to Earth.
Richard orbits the sun every 1,160 days (3.18 years), coming as close as 1.78 AU and reaching as far as 2.55 AU from the sun. Richard is about 4.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.
Richard's spectral type None (Tholen) / S (SMASSII) indicates that it is likely to contain and .
No Close Approaches
Richard's orbit is 0.77 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
Richard's orbit is determined by observations dating back to Dec. 10, 1950. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 3,363 observations used to determine its orbit.
Accessibility and Exploration
This asteroid is not considered a viable target for human exploration by the NHATS study.Similar Objects
