Overview
2005 FG is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2005 FG 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.
2005 FG orbits the sun every 434 days (1.19 years), coming as close as 0.88 AU and reaching as far as 1.36 AU from the sun. Based on its brightness and the way it reflects light, 2005 FG is probably between 0.029 to 0.129 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2005 FG'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.
2005 FG has 23 close approaches predicted in the coming decades:

Images and Observations
2005 FG's orbit is determined by observations dating back to March 11, 2005. It was last officially observed on Oct. 5, 2018. The IAU Minor Planet Center records 68 observations used to determine its orbit.
Accessibility and Exploration
2005 FG can be reached with a journey of 354 days. This trajectory would require a delta-v of 7.252 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 83,629 potential trajectories and launch windows to this asteroid.
