307261 (2002 MS4) is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2002 MS4 as potentially hazardous because its orbit does not bring it close to Earth.
2002 MS4 orbits the sun every 98,600 days (269.95 years), coming as close as 35.65 AU and reaching as far as 47.91 AU from the sun. Based on its brightness and the way it reflects light, 2002 MS4 is probably between 501.828 to 1122.122 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to France.
2002 MS4's orbit is 34.70 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.
2002 MS4's orbit is determined by observations dating back to April 8, 1954. It was last officially observed on July 4, 2022. The IAU Minor Planet Center records 133 observations used to determine its orbit.
