Key Facts

Overview

471136 (2010 EO65) is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2010 EO65 as potentially hazardous because its orbit does not bring it close to Earth.

2010 EO65 orbits the sun every 45,800 days (125.39 years), coming as close as 14.02 AU and reaching as far as 36.08 AU from the sun. Based on its brightness and the way it reflects light, 2010 EO65 is probably between 31.085 to 69.509 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Houston.

No Close Approaches

2010 EO65's orbit is 13.00 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 EO65's orbit is determined by observations dating back to April 20, 2007. It was last officially observed on June 24, 2017. The IAU Minor Planet Center records 170 observations used to determine its orbit.

Accessibility and Exploration

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