Key Facts

Overview

55380 (2001 SB264) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 2001 SB264 as potentially hazardous because its orbit does not bring it close to Earth.

2001 SB264 orbits the sun every 1,330 days (3.64 years), coming as close as 1.65 AU and reaching as far as 3.08 AU from the sun. 2001 SB264 is about 2.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

No Close Approaches

2001 SB264's orbit is 0.80 AU from Earth's orbit at its closest point. This means that there is a very 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 SB264's orbit is determined by observations dating back to July 25, 1982. It was last officially observed on Dec. 12, 2022. The IAU Minor Planet Center records 1,182 observations used to determine its orbit.

Accessibility and Exploration

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