observations in Israel have revealed new rotation speed for the dwarf planet . Previously it was thought to rotate in 10 hours , 39 minutes and 22 seconds . But new measurements of 10 hours , 32 minutes and 22 seconds is more accurate . This is based on measuring its gravitational field , shape and density . The same method correctly calculated the rotation speed of planets .
