Solar System Planets  

In General > s.a. earth; history of astronomy; orbits of gravitating bodies [including cosmological effects].
* Formation: Probably together with, or shortly after a star, from leftover gas and dust, by formation and merger of protoplanets; Turbulent and poorly understood; However, it seems that planet formation is easy, and is a mechanism for loss of angular momentum for the star.
* History: In the III century BC Epicurus wrote to Herodotus about the infinitely many worlds, probably inhabited; According to Aristotelians a moving body could not be the center of another movement; When Galileo discovered Jupiter's satellites, some said that they were illusions created by the telescope (others laughed).
* Moons: Most of them probably formed from rings around the planets, possibly including Earth's moon.
* Prebiological conditions: Titan (Saturn), Europa (Jupiter).
