  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

89829 (2002 BQ29) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2002 BQ29 as potentially hazardous because its orbit does not bring it close to Earth.

2002 BQ29 orbits the sun every 4,360 days (11.94 years), coming as close as 4.96 AU and reaching as far as 5.49 AU from the sun. 2002 BQ29 is about 17.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.

No Close Approaches

2002 BQ29's orbit is 3.95 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

2002 BQ29's orbit is determined by observations dating back to Dec. 21, 2000. It was last officially observed on Jan. 24, 2023. The IAU Minor Planet Center records 895 observations used to determine its orbit.

Accessibility and Exploration

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