Key Facts

Overview

469704 (2005 EZ296) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2005 EZ296 as potentially hazardous because its orbit does not bring it close to Earth.

2005 EZ296 orbits the sun every 89,600 days (245.31 years), coming as close as 33.49 AU and reaching as far as 44.91 AU from the sun. Based on its brightness and the way it reflects light, 2005 EZ296 is probably between 100.128 to 223.893 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Connecticut.

No Close Approaches

2005 EZ296's orbit is 32.50 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 EZ296's orbit is determined by observations dating back to Dec. 23, 2000. It was last officially observed on June 2, 2022. The IAU Minor Planet Center records 245 observations used to determine its orbit.

Accessibility and Exploration

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