Ceres

Is Pluto bigger than Eris?
Those put Eris’ diameter at 1,490 miles (2,397 km) — bigger than Pluto — with an uncertainty of 100 km. The best measure we have now was made by stellar occultations. These put Eris’ diameter at 1,451 miles (2,336 km) — smaller than Pluto — with a reported uncertainty of 7 miles (12 km).
