Overview

2014 WP201 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 WP201 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2014 WP201 orbits the sun every 776 days (2.12 years), coming as close as 0.66 AU and reaching as far as 2.64 AU from the sun. Based on its brightness and the way it reflects light, 2014 WP201 is probably between 0.221 to 0.494 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2014 WP201's orbit is 0.09 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2014 WP201 has 10 close approaches predicted in the coming decades:
