Key Facts


416180 (2002 SB54) is a small asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 2002 SB54 as potentially hazardous because its orbit does not bring it close to Earth.

2002 SB54 orbits the sun every 2,036 days (5.58 years), coming as close as 2.28 AU and reaching as far as 4.01 AU from the sun. Based on its brightness and the way it reflects light, 2002 SB54 is probably between 1.756 to 3.927 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to Mount Everest.

No Close Approaches

2002 SB54's orbit is 1.31 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 SB54's orbit is determined by observations dating back to Aug. 17, 2002. It was last officially observed on Aug. 3, 2018. The IAU Minor Planet Center records 95 observations used to determine its orbit.

Accessibility and Exploration

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