Here is an inner planets map area according to Vibes of Cosmos which I subscribe to more than the Nos Confunden map.

The Sun, in yellow, is in our known area keeping us lit and warm. The Moon, which is further out and gives a cold light, covers most of the Terra Vista landmass beyond our antarctic perimeter. Even the shape of it looks like a crescent Moon.

Beyond this is an unfrozen ring area which Vibes of Cosmos assigns to the planet/body Mercury. Apparently, Mercury gives enough light and heat to keep this area unfrozen. Then there is a frozen ring area followed by another unfrozen ring area which Vibes of Cosmos assigns to the planet Venus, Apparently Venus too gives off enough light and heat to keep its corresponding area unfrozen.

Beyond Venus is the Mars ring/realm, in which we are nested, and beyond that are the much larger Jupiter, Saturn, Uranus, etc. land rings/areas, which make our entire level landmass truly vast.
