I'm not entirely sure because the website is in Japanese, but it appears that a chocolatier called L’éclat offers chocolate versions of the planets of our solar system. Sadly, they're not to scale, or else I'd call dibs on Jupiter!

Venus - lemon cream
Earth - chocolate (cocoa)
Mars- orange praline
Jupiter - vanilla
Saturn- rum raisin
