  • Categorized as a Jupiter Trojan
  • Comparable in size to the city of Indianapolis (24.48 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

23939 (1998 TV33) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1998 TV33 as potentially hazardous because its orbit does not bring it close to Earth.

1998 TV33 orbits the sun every 4,200 days (11.50 years), coming as close as 4.88 AU and reaching as far as 5.32 AU from the sun. 1998 TV33 is about 24.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

The rotation of 1998 TV33 has been observed. It completes a rotation on its axis every 12.87 hours.

No Close Approaches

1998 TV33's orbit is 3.89 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

1998 TV33's orbit is determined by observations dating back to Dec. 7, 1988. It was last officially observed on April 8, 2023. The IAU Minor Planet Center records 1,881 observations used to determine its orbit.

Accessibility and Exploration

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