Overview
90403 (2003 YE45) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2003 YE45 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2003 YE45 orbits the sun every 501 days (1.37 years), coming as close as 0.89 AU and reaching as far as 1.58 AU from the sun. 2003 YE45 is about 0.6 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.
The rotation of 2003 YE45 has been observed. It completes a rotation on its axis every 505.00 hours.
Close Approaches
2003 YE45's orbit is 0.04 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.
2003 YE45 has 9 close approaches predicted in the coming decades:
