The two planets turned out to be connected by gravity. They do not move away or get closer to each other, but can move in a circular orbit in Orbit Tap Rush. Planets need to settle down somewhere in order to develop life. But you will have to fly and look for a secluded place near some hot star. While moving, make sure that none of the planets collide with yellow objects. Every thirty seconds a star will appear, it is better to hit it so that one of the celestial bodies becomes invulnerable for a while in Orbit Tap Rush.
