Key Facts

  • Categorized as a Main-belt Asteroid
  • Comparable in size to the U.S. state of Rhode Island (57.52 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

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

Carolina orbits the sun every 1,790 days (4.90 years), coming as close as 2.71 AU and reaching as far as 3.06 AU from the sun. Carolina is about 57.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of Carolina has been observed. It completes a rotation on its axis every 17.61 hours.

No Close Approaches

Carolina's orbit is 1.69 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

Carolina's orbit is determined by observations dating back to Feb. 13, 1884. It was last officially observed on July 5, 2023. The IAU Minor Planet Center records 11,866 observations used to determine its orbit.

Accessibility and Exploration

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