Key Facts

  • Categorized as a Jupiter Trojan
  • Comparable in size to the city of Denver (19.59 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

39794 (1997 SU24) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1997 SU24 as potentially hazardous because its orbit does not bring it close to Earth.

1997 SU24 orbits the sun every 4,300 days (11.77 years), coming as close as 5.02 AU and reaching as far as 5.34 AU from the sun. 1997 SU24 is about 19.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Denver.

No Close Approaches

1997 SU24's orbit is 4.03 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

1997 SU24's orbit is determined by observations dating back to Oct. 9, 1996. It was last officially observed on Jan. 13, 2023. The IAU Minor Planet Center records 903 observations used to determine its orbit.

Accessibility and Exploration

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