Key Facts


120216 (2004 EW95) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2004 EW95 as potentially hazardous because its orbit does not bring it close to Earth.

2004 EW95 orbits the sun every 90,800 days (248.60 years), coming as close as 26.98 AU and reaching as far as 52.06 AU from the sun. Based on its brightness and the way it reflects light, 2004 EW95 is probably between 126.635 to 283.165 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Vermont.

No Close Approaches

2004 EW95's orbit is 26.00 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

2004 EW95's orbit is determined by observations dating back to March 12, 2001. It was last officially observed on June 15, 2020. The IAU Minor Planet Center records 280 observations used to determine its orbit.

Accessibility and Exploration

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