Key Facts

Overview

566442 (2018 EZ1) is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2018 EZ1 as potentially hazardous because its orbit does not bring it close to Earth.

2018 EZ1 orbits the sun every 23,700 days (64.89 years), coming as close as 9.86 AU and reaching as far as 22.40 AU from the sun. Based on its brightness and the way it reflects light, 2018 EZ1 is probably between 12.959 to 28.976 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Philadelphia.

No Close Approaches

2018 EZ1's orbit is 8.87 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

2018 EZ1's orbit is determined by observations dating back to Dec. 26, 2014. It was last officially observed on April 25, 2023. The IAU Minor Planet Center records 130 observations used to determine its orbit.

Accessibility and Exploration

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