2021 LF6 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2021 LF6 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.
2021 LF6 orbits the sun every 356 days (0.97 years), coming as close as 0.95 AU and reaching as far as 1.02 AU from the sun. Based on its brightness and the way it reflects light, 2021 LF6 is probably between 0.003 to 0.015 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2021 LF6's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2021 LF6's orbit is determined by observations dating back to June 12, 2021. It was last officially observed on June 27, 2021. The IAU Minor Planet Center records 27 observations used to determine its orbit.
2021 LF6 can be reached with a journey of 370 days. This trajectory would require a delta-v of 3.61 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 1,698,447 potential trajectories and launch windows to this asteroid.
