Overview
2018 LF5 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2018 LF5 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2018 LF5 orbits the sun every 1,700 days (4.65 years), coming as close as 1.07 AU and reaching as far as 4.52 AU from the sun. Based on its brightness and the way it reflects light, 2018 LF5 is probably between 0.242 to 0.542 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to a football field.
Close Approaches
2018 LF5's orbit is 0.05 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.
2018 LF5 has 1 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| June 25, 2175 | 22,849,037 | 24.977 |
Images and Observations
2018 LF5's orbit is determined by observations dating back to May 19, 2018. It was last officially observed on Oct. 15, 2018. The IAU Minor Planet Center records 239 observations used to determine its orbit.
