Overview

138175 (2000 EE104) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 EE104 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2000 EE104 orbits the sun every 368 days (1.01 years), coming as close as 0.71 AU and reaching as far as 1.30 AU from the sun. Based on its brightness and the way it reflects light, 2000 EE104 is probably between 1.520 to 6.780 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the island of Manhattan.

Close Approaches

2000 EE104's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2000 EE104 has 29 close approaches predicted in the coming decades:

Images and Observations

2000 EE104's orbit is determined by observations dating back to March 11, 2000. It was last officially observed on Jan. 16, 2019. The IAU Minor Planet Center records 942 observations used to determine its orbit.

Accessibility and Exploration

2000 EE104 can be reached with a journey of 426 days. This trajectory would require a delta-v of 9.972 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 22,745 potential trajectories and launch windows to this asteroid.
