Key Facts

Overview

89898 (2002 CY279) is a mid-sized asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2002 CY279 as potentially hazardous because its orbit does not bring it close to Earth.

2002 CY279 orbits the sun every 4,230 days (11.58 years), coming as close as 4.95 AU and reaching as far as 5.28 AU from the sun. Based on its brightness and the way it reflects light, 2002 CY279 is probably between 5.427 to 12.135 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

No Close Approaches

2002 CY279's orbit is 3.97 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 CY279's orbit is determined by observations dating back to Oct. 27, 1998. It was last officially observed on Jan. 11, 2023. The IAU Minor Planet Center records 499 observations used to determine its orbit.

Accessibility and Exploration

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