Overview

2019 LG1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 LG1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2019 LG1 orbits the sun every 437 days (1.20 years), coming as close as 0.72 AU and reaching as far as 1.53 AU from the sun. Based on its brightness and the way it reflects light, 2019 LG1 is probably between 0.184 to 0.411 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2019 LG1'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.

2019 LG1 has 22 close approaches predicted in the coming decades:
