2019 LB is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 LB 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.
2019 LB orbits the sun every 476 days (1.30 years), coming as close as 1.01 AU and reaching as far as 1.37 AU from the sun. Based on its brightness and the way it reflects light, 2019 LB is probably between 0.160 to 0.720 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to the U.S. Capitol building.
2019 LB's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
2019 LB has 6 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|June 12, 2019||3,494,113||6.046|
|June 4, 2049||15,914,663||7.955|
|June 18, 2062||9,866,343||5.574|
|May 30, 2079||29,866,194||10.166|
|June 6, 2109||12,352,789||7.454|
|June 8, 2182||10,731,962||7.237|
2019 LB's orbit is determined by observations dating back to May 7, 2019. It was last officially observed on June 7, 2019. The IAU Minor Planet Center records 70 observations used to determine its orbit.
2019 LB can be reached with a journey of 362 days. This trajectory would require a delta-v of 9.279 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 872 potential trajectories and launch windows to this asteroid.
