Overview

2017 EE23 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2017 EE23 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.

2017 EE23 orbits the sun every 299 days (0.82 years), coming as close as 0.54 AU and reaching as far as 1.21 AU from the sun. Based on its brightness and the way it reflects light, 2017 EE23 is probably between 0.116 to 0.259 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.

Close Approaches

2017 EE23's orbit is 0.05 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

2017 EE23 has 15 close approaches predicted in the coming decades:
