(Not) optional

Add white holes (the opist of a black hole) and get 5 stars

Love the Apple Watch implementation

I love the… animation of a slightly eccentric orbit going round and round for all of eternity. Not to mention that the center object doesn’t move a pixel which is unrealistic! 10/10 Apple Watch support, so much fun watching the animation and… yeah!
