363401 (2003 LB7) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2003 LB7 as potentially hazardous because its orbit does not bring it close to Earth.
2003 LB7 orbits the sun every 112,000 days (306.64 years), coming as close as 39.71 AU and reaching as far as 51.49 AU from the sun. Based on its brightness and the way it reflects light, 2003 LB7 is probably between 120.936 to 270.421 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Vermont.
2003 LB7's orbit is 38.70 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
2003 LB7's orbit is determined by observations dating back to June 1, 2003. It was last officially observed on April 12, 2018. The IAU Minor Planet Center records 52 observations used to determine its orbit.
