Overview
2014 GJ1 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2014 GJ1 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 GJ1 orbits the sun every 334 days (0.91 years), coming as close as 0.69 AU and reaching as far as 1.20 AU from the sun. Based on its brightness and the way it reflects light, 2014 GJ1 is probably between 0.025 to 0.112 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2014 GJ1's orbit is 0.03 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.
2014 GJ1 has 28 close approaches predicted in the coming decades:

Images and Observations
2014 GJ1's orbit is determined by observations dating back to April 1, 2014. It was last officially observed on April 26, 2014. The IAU Minor Planet Center records 44 observations used to determine its orbit.
Accessibility and Exploration
2014 GJ1 can be reached with a journey of 386 days. This trajectory would require a delta-v of 9.086 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 48,480 potential trajectories and launch windows to this asteroid.
