The minor planet center is the clearing house of observations of objects in our solar system. They have announced a new dwarf planet today.
This object appears to be in a very eccentric orbit (0.948), and with an H magnitude of 3.55, so it is likely hundreds of km in diameter.
Ceres for reference has a H magnitude of 3.33 (smaller H is bigger diameter).
