This star mobile is a beautiful way to create a constellation of stars and planets. Though Robert only uses stars for his mobile, you can try incorporating different shapes, like moons or planets depending on what silicone molds you find, into your mobile.
Or, you can depart from the space theme entirely and opt for a different look with animals, flowers, or whatever your heart desires. It might even be fun to use letter-shaped molds to spell out a name.
