We have opened a new planet in our Watermelon Saturn Sticker! In a galaxy far away, there is a planet that looks like a ripe watermelon, a large, round fruit with dark green skin, sweet red flesh, and a lot of black seeds. But we doubt you can eat it like the usual watermelon you got used to seeing in summer. One way or another, it is a planet with a green satellite. Like Saturn from our Solar System, Watermelon Saturn is the sixth planet from the Sun and the second-largest in the Fruit System.
