Overview

358453 (2007 EH88) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 EH88 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.

2007 EH88 orbits the sun every 434 days (1.19 years), coming as close as 0.63 AU and reaching as far as 1.62 AU from the sun. Based on its brightness and the way it reflects light, 2007 EH88 is probably between 0.282 to 0.631 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

2007 EH88's orbit is 0.13 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.

2007 EH88 has 12 close approaches predicted in the coming decades:
