Key Facts

  • Categorized as a Main-belt Asteroid
  • Comparable in size to the U.S. state of Rhode Island (54.73 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

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

Russia orbits the sun every 1,490 days (4.08 years), coming as close as 2.11 AU and reaching as far as 3.00 AU from the sun. Russia is about 54.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of Russia has been observed. It completes a rotation on its axis every 21.91 hours.

Russia's spectral type C (Tholen) / None (SMASSII) indicates that it is likely to contain water, iron, nickel, cobalt, nitrogen, and ammonia.

No Close Approaches

Russia's orbit is 1.11 AU from Earth's orbit at its closest point. This means that there is an extremely 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

Russia's orbit is determined by observations dating back to Sept. 24, 1913. It was last officially observed on April 27, 2021. The IAU Minor Planet Center records 3,356 observations used to determine its orbit.

Accessibility and Exploration

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