Overview

450300 (2004 QD14) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2004 QD14 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2004 QD14 orbits the sun every 334 days (0.91 years), coming as close as 0.62 AU and reaching as far as 1.26 AU from the sun. Based on its brightness and the way it reflects light, 2004 QD14 is probably between 0.128 to 0.571 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 QD14's orbit is 0.01 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.

2004 QD14 has 24 close approaches predicted in the coming decades:
