Key Facts

  • Categorized as a Main-belt Asteroid
  • Comparable in size to the U.S. state of Rhode Island (61.31 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

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

Nike orbits the sun every 1,810 days (4.96 years), coming as close as 2.49 AU and reaching as far as 3.32 AU from the sun. Nike is about 61.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of Nike has been observed. It completes a rotation on its axis every 11.86 days.

No Close Approaches

Nike's orbit is 1.51 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

Nike's orbit is determined by observations dating back to March 5, 1891. It was last officially observed on June 17, 2020. The IAU Minor Planet Center records 3,171 observations used to determine its orbit.

Accessibility and Exploration

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