Key Facts

Overview

51360 (2000 SZ25) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2000 SZ25 as potentially hazardous because its orbit does not bring it close to Earth.

2000 SZ25 orbits the sun every 4,280 days (11.72 years), coming as close as 4.88 AU and reaching as far as 5.45 AU from the sun. Based on its brightness and the way it reflects light, 2000 SZ25 is probably between 9.132 to 20.419 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Cleveland, Ohio.

No Close Approaches

2000 SZ25's orbit is 3.87 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

2000 SZ25's orbit is determined by observations dating back to June 10, 1999. It was last officially observed on June 27, 2023. The IAU Minor Planet Center records 925 observations used to determine its orbit.

Accessibility and Exploration

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