Overview

450270 (2004 AE) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2004 AE as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2004 AE orbits the sun every 626 days (1.71 years), coming as close as 0.96 AU and reaching as far as 1.91 AU from the sun. Based on its brightness and the way it reflects light, 2004 AE is probably between 0.202 to 0.451 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2004 AE's orbit is 0.02 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 AE has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Jan. 10, 2028 27,552,884 14.182
Feb. 15, 2105 23,817,267 12.001
Feb. 12, 2117 19,719,641 11.798
Feb. 12, 2129 20,316,093 11.813
Feb. 17, 2141 25,459,047 12.090
