I'm not famous.

The word "Equus" as the name of their planet is not canon, but this view of the planet from space presumably is what it looks like in canon.That said, we're never going to get an official answer on the name of their planet because the show doesn't really focus on super science-y things like that. So in the absence of any kind of canon planet name, "Equus" will continue to do just fine as it has for the past few years.
