Overview

357621 (2005 EG94) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2005 EG94 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.

2005 EG94 orbits the sun every 742 days (2.03 years), coming as close as 0.86 AU and reaching as far as 2.35 AU from the sun. Based on its brightness and the way it reflects light, 2005 EG94 is probably between 0.460 to 1.028 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2005 EG94's orbit is 0.06 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.

2005 EG94 has 12 close approaches predicted in the coming decades:
