Mercury

The video explores Mercury, the closest planet to the sun, highlighting its rapid orbit, unique spin-orbit resonance, and challenging visibility. It discusses historical observations, surface features, and internal structure, including its large iron core and magnetic field. Despite its proximity to the sun, Mercury has water ice in polar craters. Observations from space probes like Mariner 10 and MESSENGER have provided insights into its cratered surface and impact dynamics. The video concludes with a summary of Mercury's characteristics and credits to the production team.
