Overview

2003 FF5 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2003 FF5 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.

2003 FF5 orbits the sun every 586 days (1.60 years), coming as close as 0.95 AU and reaching as far as 1.79 AU from the sun. Based on its brightness and the way it reflects light, 2003 FF5 is probably between 0.400 to 1.780 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2003 FF5's orbit is 0.03 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.

2003 FF5 has 14 close approaches predicted in the coming decades:

Images and Observations

2003 FF5's orbit is determined by observations dating back to March 27, 2003. It was last officially observed on Aug. 8, 2019. The IAU Minor Planet Center records 158 observations used to determine its orbit.

Accessibility and Exploration

2003 FF5 can be reached with a journey of 346 days. This trajectory would require a delta-v of 11.085 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 484 potential trajectories and launch windows to this asteroid.
