Key Facts

Overview

11549 (1992 YY) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1992 YY as potentially hazardous because its orbit does not bring it close to Earth.

1992 YY orbits the sun every 1,470 days (4.02 years), coming as close as 2.31 AU and reaching as far as 2.75 AU from the sun. 1992 YY is about 10.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.

The rotation of 1992 YY has been observed. It completes a rotation on its axis every 2.67 hours.

No Close Approaches

1992 YY's orbit is 1.30 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

1992 YY's orbit is determined by observations dating back to Oct. 29, 1959. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 3,129 observations used to determine its orbit.

Accessibility and Exploration

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