Key Facts
- Categorized as a Main-belt Asteroid
- Comparable in size to Mount Everest (2.44 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Rasa is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Rasa as potentially hazardous because its orbit does not bring it close to Earth.
Rasa orbits the sun every 1,160 days (3.18 years), coming as close as 1.98 AU and reaching as far as 2.34 AU from the sun. Rasa is about 2.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.
No Close Approaches
Rasa's orbit is 0.98 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
Rasa's orbit is determined by observations dating back to Feb. 19, 1977. It was last officially observed on Aug. 24, 2022. The IAU Minor Planet Center records 1,751 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
