Key Facts

  • Categorized as a Main-belt Asteroid
  • Comparable in size to the U.S. state of Rhode Island (43.58 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

Sarita is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Sarita as potentially hazardous because its orbit does not bring it close to Earth.

Sarita orbits the sun every 1,560 days (4.27 years), coming as close as 1.79 AU and reaching as far as 3.48 AU from the sun. Sarita is about 43.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of Sarita has been observed. It completes a rotation on its axis every 8.18 hours.

Sarita's spectral type XD (Tholen) / X (SMASSII) indicates that it is likely to contain iron, nickel, and cobalt.

No Close Approaches

Sarita's orbit is 0.81 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

Sarita's orbit is determined by observations dating back to Oct. 16, 1914. It was last officially observed on June 30, 2023. The IAU Minor Planet Center records 12,975 observations used to determine its orbit.

Accessibility and Exploration

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