Key Facts

Overview

157471 (2005 AX71) is a mid-sized asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2005 AX71 as potentially hazardous because its orbit does not bring it close to Earth.

2005 AX71 orbits the sun every 4,350 days (11.91 years), coming as close as 4.61 AU and reaching as far as 5.82 AU from the sun. Based on its brightness and the way it reflects light, 2005 AX71 is probably between 4.904 to 10.966 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

No Close Approaches

2005 AX71's orbit is 3.60 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

2005 AX71's orbit is determined by observations dating back to Aug. 7, 1999. It was last officially observed on June 27, 2023. The IAU Minor Planet Center records 264 observations used to determine its orbit.

Accessibility and Exploration

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