Overview

162063 (1997 EH29) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1997 EH29 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.

1997 EH29 orbits the sun every 489 days (1.34 years), coming as close as 0.40 AU and reaching as far as 2.02 AU from the sun. Based on its brightness and the way it reflects light, 1997 EH29 is probably between 0.431 to 0.964 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

1997 EH29's orbit is 0.15 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.

1997 EH29 has 7 close approaches predicted in the coming decades:
