God's Orbits comes from Alexandre La Boissonniere. It's a physics/astronomy puzzle.  The object is to place the orbs so that they will complete 1 revolution around the sun.
Alexandre's description:
God has been making planets and stars orbit around each other for billions of years. But as any normal person, He now needs a break. So, as God takes a week?s vacation and goes to Cancún, you need to replace Him and do His job.The game is a gravity simulation based on Newton?s law of universal gravity where you control the speed and direction of a single planet. You?ll need to find the precise trajectory of this planet to make it orbit around another celestial body.A lot of features are offered to diversify the different challenges at hand.Features:? Every planet in our solar system? Suns? Antimatter stars? Neutron stars? Wormholes? Black holesThe game contains a total of 60 levels (and more to come). The first 7 are free and all the others can be unlocked with one single purchase.
I've done levels 1-5. I'm stuck on 6.  It's all guess and check and then watch the orbs either collide or fall into the sun. I'm stuck on level 7 too. It's very cool though.

Of those levels, I didn't encounter antimatter stars or neutron stars or black holes.  I like the concept a lot. But it's not a pure logic puzzle.  https://itunes.apple.com/us/app/gods-orbits/id1425232612"mt=8
