Radiometric dating of these rocks shows that the Moon is 4.53 ± 0.01 billion years old, [46] formed at least 30 million years after the Solar System. [47] New evidence suggests the Moon formed even later, 4.48 ± 0.02 Ga, or 70–110 million years after the start of the Solar System. [48]
Consequently, he introduced a new system, the Tychonic system, in which the Earth was still at the center of the universe, and around it revolved the Sun, but all the other planets revolved around the Sun in a set of epicycles.
