C/1840 B1 (Galle) is a large comet whose orbit does not match any defined comet orbit class. NASA JPL has not classified Galle as potentially hazardous because its orbit does not bring it close to Earth.
Galle orbits the sun every 0 days (0.00 years), coming as close as 1.23 AU and reaching as far as 360.37 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, Galle is probably between 2658.000 to 5943.469 kilometers in diameter, making it the largest asteroid/dwarf planet, very roughly comparable in size to the U.S. state of Alaska.
Galle's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
Galle's orbit is determined by observations dating back to Jan. 25, 1840. It was last officially observed on April 3, 1840. The IAU Minor Planet Center records 78 observations used to determine its orbit.
