Overview
2019 LZ1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 LZ1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2019 LZ1 orbits the sun every 1,220 days (3.34 years), coming as close as 0.17 AU and reaching as far as 4.30 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2019 LZ1 is probably between 0.286 to 0.640 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.
Close Approaches
2019 LZ1'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.
2019 LZ1 has 11 close approaches predicted in the coming decades:
