Key Facts

Overview

5528 (1992 AJ) is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 1992 AJ as potentially hazardous because its orbit does not bring it close to Earth.

1992 AJ orbits the sun every 2,140 days (5.86 years), coming as close as 3.10 AU and reaching as far as 3.40 AU from the sun. 1992 AJ is about 21.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

No Close Approaches

1992 AJ's orbit is 2.12 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 AJ's orbit is determined by observations dating back to Sept. 28, 1954. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 3,697 observations used to determine its orbit.

Accessibility and Exploration

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