Figure 14-20: The Largest Trans-Neptunian Objects This artist’s impression depicts Earth and the largest objects known beyond Neptune (as of 2012) to the same scale. The largest of these, Eris, has a diameter between 2300 km and 2400 km. There is less uncertainty about Pluto’s diameter, which is close to 2300 km. Note the differences in color among these objects and that five of them have satellites of their own. Table 7-4 in Section 7-5 lists the properties of seven of these objects.
