           These four panels show the location of  trans-Neptunian object  90377 Sedna, which lies in the farthest reaches of the  Solar system. Each panel, moving clockwise from the upper left, successively zooms out to place Sedna in context. The first panel shows the  orbits of the inner  planets and  Jupiter; and the  asteroid belt. In the second panel, Sedna is shown well outside the orbits of  Neptune and the  Kuiper belt objects. 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. Sedna's presence suggests that the previously speculated inner disk on the  ecliptic does exist.  |
