Overview
419472 (2010 DW1) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 DW1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2010 DW1 orbits the sun every 495 days (1.36 years), coming as close as 0.98 AU and reaching as far as 1.47 AU from the sun. 2010 DW1 is about 0.5 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, comparable in size to the U.S. Capitol building.
Close Approaches
2010 DW1'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.
2010 DW1 has 8 close approaches predicted in the coming decades:
