Key Facts

  • Categorized as a Jupiter Trojan
  • Comparable in size to the city of Indianapolis (23.78 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

38606 (1999 YC13) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1999 YC13 as potentially hazardous because its orbit does not bring it close to Earth.

1999 YC13 orbits the sun every 4,280 days (11.72 years), coming as close as 4.83 AU and reaching as far as 5.48 AU from the sun. 1999 YC13 is about 23.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

No Close Approaches

1999 YC13's orbit is 3.85 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

1999 YC13's orbit is determined by observations dating back to Nov. 11, 1998. It was last officially observed on March 18, 2023. The IAU Minor Planet Center records 1,200 observations used to determine its orbit.

Accessibility and Exploration

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