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

Overview

63955 (2001 SP65) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2001 SP65 as potentially hazardous because its orbit does not bring it close to Earth.

2001 SP65 orbits the sun every 4,300 days (11.77 years), coming as close as 4.51 AU and reaching as far as 5.84 AU from the sun. 2001 SP65 is about 22.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

No Close Approaches

2001 SP65's orbit is 3.52 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

2001 SP65's orbit is determined by observations dating back to April 23, 1995. It was last officially observed on Oct. 29, 2022. The IAU Minor Planet Center records 1,150 observations used to determine its orbit.

Accessibility and Exploration

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