This model-menu is an update of the SISV’s previous version that presented information to 2007. It graphically represents the dimensions of the Kuiper Belt and the orbits of the 7 largest Trans-Neptunian Objects (TNOs), known as of 2021. Neptune's orbit is represented as reference.

Although Ceres is also a dwarf planet, it is not represented here as it belongs to the Asteroid Belt group.

Only the maps of Neptune and Pluto are realistic, all others are fictional. *
