The Planet Hoth
A planet exactly like Hoth can actually exist, something George Lucas likely did not know back in the 1970s. In fact, we’ve found MANY Hoth-like planets. They are pretty interesting. On our Earth, tectonics and even forming reservoirs of magma create volcanoes whenever this magma finds its way to the surface. That gives us rock. However, in planets without atmospheres like our own, ice manages to become very cold and will operate exactly like rock does on Earth. This is exactly what you see in Saturn’s moon, Titan. They have rivers of methane and ethane that produce a crust of watery ice-rock.
These icy worlds are often a further distance from their star. But there are some near dwarf stars, allowing them to be closer to their star. Yet Hoth is not like the previous icy world example, rather, it would technically be a “Snowball Earth.” This has existed in the past when our Earth was frozen. In this time, the Earth made ice and snow and slowly continue to reflect sunlight back, causing even more freezing. Yet the last time this happened on Earth, we did not have the oceans we see today. Therefore, life was likely microbial if present at all. This means Hoth could exist but would be a bit different.
