Overview

2002 FW1 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2002 FW1 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.

2002 FW1 orbits the sun every 273 days (0.75 years), coming as close as 0.54 AU and reaching as far as 1.11 AU from the sun. Based on its brightness and the way it reflects light, 2002 FW1 is probably between 0.033 to 0.074 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2002 FW1'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.

2002 FW1 has 7 close approaches predicted in the coming decades:
