Eternia scaled one in sixty million by tato_713

Last crawled date: 4 years, 1 month ago
This is the planet of the Masters of the Universe series, including He-Man and She-Ra. I did this in order to take advantage of near upcoming nippled Netflix reboot of the serie. This is easily the most cartoonish model I've ever made, since there are not so many topological features recognisable from space, so I exaggerate some placed to be seen in the model. For example, there is a tiny cube representing the Grayskull Castle, that, if it was scaled, it would size about 40 km long.
The file's names explained: name_1_x_10_y.stl is 1 : x * 10y. So _1_6_10_7 is 1:600000000 or one in 60 million.
The size of Eternia
Like most of fantasy planets, a clear reference about its size is absent, and like most of these stories, the time it takes to travel between different parts is inconsistent with planetary sizes. But in order to get a decent planet sized planet, I take one measure I read in this blog of "a third smaller" than Earth, that is, a diameter between Mars and Venus. This comes from an UK MotU Comic, which I have not access, so I cannot verify it.
A side note about the "environment" of Eternia is that there is a "light hemisphere" and a "dark hemisphere". That, for astronomy enthusiast like moi, is an obvious sign of a tidal locked planet. It was theorized that an abundant atmosphere could make a tidal locked planet fully habitable. However, I saw a few episodes, and it seems to be a day cycle, at least, in the "light side". This can be explained with a moderately eccentric orbit, like Mercury's, making a "tumbling" movement, because of the different velocities during along the orbit path, resulting in a pseudo-day cycle in the terminator line longitudes.
