  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Asteroid (PHA)
  • See orbit simulation

Overview

2017 EV2 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 EV2 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 collision.

2017 EV2 orbits the sun every 371 days (1.02 years), coming as close as 0.45 AU and reaching as far as 1.57 AU from the sun. Based on its brightness and the way it reflects light, 2017 EV2 is probably between 0.18 to 0.41 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2017 EV2's orbit is 0.12 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 EV2 has 75 close approaches predicted in the coming decades:
