Lempo is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified Lempo as potentially hazardous because its orbit does not bring it close to Earth.
Lempo orbits the sun every 90,300 days (247.23 years), coming as close as 30.54 AU and reaching as far as 48.24 AU from the sun. Based on its brightness and the way it reflects light, Lempo is probably between 291.444 to 651.688 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to the U.S. state of Iowa.
The rotation of Lempo has been observed. It completes a rotation on its axis every 6.21 hours.
Lempo's orbit is 29.60 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.
Lempo's orbit is determined by observations dating back to June 18, 1974. It was last officially observed on Nov. 10, 2020. The IAU Minor Planet Center records 615 observations used to determine its orbit.
