Key Facts

Overview

418265 (2008 EA32) is a mid-sized asteroid with an orbit that is entirely confined within Earth's orbit. NASA JPL has classified 2008 EA32 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2008 EA32 orbits the sun every 177 days (0.48 years), coming as close as 0.43 AU and reaching as far as 0.80 AU from the sun. Based on its brightness and the way it reflects light, 2008 EA32 is probably between 1.332 to 2.979 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

No Close Approaches

2008 EA32's orbit is 0.18 AU from Earth's orbit at its closest point. This means that there is an 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

2008 EA32's orbit is determined by observations dating back to March 10, 2008. It was last officially observed on April 25, 2021. The IAU Minor Planet Center records 234 observations used to determine its orbit.

Accessibility and Exploration

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