Sedna is nearing its closest approach to the Sun; its 10,000 year orbit typically takes it to far greater distances. The final panel zooms out much farther, showing that even this large elliptical orbit falls inside what was previously thought to be the inner edge of the Oort cloud. The long cyan oval indicates the orbit of Sedna, the red dot shows the current position of Sedna in its orbit. Sedna is a trans-neputian dwarf planet located in the Oort cloud and is one of the most distant known objects in the solar system. It is not officially recognized as a dwarf planet.yet. Sedna's exceptionally long and elongated orbit, taking approximately 11,400 years to complete, and distant point of closest approach to the Sun, at 76 AU, have led to much speculation as to its origin. Sedna's full orbit is illustrated in the third panel along with the object's location in 2004, nearing its closest approach to the Sun. The final panel zooms out much farther, showing that even this large elliptical orbit falls inside what was previously thought to be the inner edge of the spherical Oort cloud: a distribution of cold, icy bodies lying at the limits of the Sun's gravitational pull.
