| 27. | Ceres as well as Pluto and several other large Trans-Neptunian objects belong to this category.
|
| 28. | He predicted the existence of a trans-Neptunian planet fifty years before the discovery of Pluto.
|
| 29. | Assuming a generic trans-Neptunian albedo of 0.09, it is about in diameter.
|
| 30. | Some large asteroids and other named trans-Neptunian objects make use of this template as well.
