Overview

357594 (2004 XL35) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2004 XL35 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2004 XL35 orbits the sun every 576 days (1.58 years), coming as close as 0.98 AU and reaching as far as 1.73 AU from the sun. Based on its brightness and the way it reflects light, 2004 XL35 is probably between 0.314 to 0.702 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

2004 XL35's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2004 XL35 has 8 close approaches predicted in the coming decades:
