Key Facts

Overview

471152 (2010 FE49) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2010 FE49 as potentially hazardous because its orbit does not bring it close to Earth.

2010 FE49 orbits the sun every 142,000 days (388.77 years), coming as close as 33.61 AU and reaching as far as 72.95 AU from the sun. Based on its brightness and the way it reflects light, 2010 FE49 is probably between 133.216 to 297.879 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Massachusetts.

No Close Approaches

2010 FE49's orbit is 32.60 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

2010 FE49's orbit is determined by observations dating back to March 29, 2008. It was last officially observed on May 15, 2023. The IAU Minor Planet Center records 294 observations used to determine its orbit.

Accessibility and Exploration

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