Key Facts

  • Categorized as a Jupiter Trojan
  • Comparable in size to the city of Philadelphia (18.41 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

17416 (1988 RR10) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1988 RR10 as potentially hazardous because its orbit does not bring it close to Earth.

1988 RR10 orbits the sun every 4,250 days (11.64 years), coming as close as 4.81 AU and reaching as far as 5.46 AU from the sun. 1988 RR10 is about 18.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.

The rotation of 1988 RR10 has been observed. It completes a rotation on its axis every 40.97 hours.

No Close Approaches

1988 RR10's orbit is 3.83 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

1988 RR10's orbit is determined by observations dating back to Sept. 14, 1988. It was last officially observed on June 14, 2023. The IAU Minor Planet Center records 1,053 observations used to determine its orbit.

Accessibility and Exploration

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