Uranus & Neptune

The video explores Uranus and Neptune, the ice giants of our solar system. Uranus was discovered by William Herschel in 1781, while Neptune was found through mathematical prediction in 1846. Both planets have small rocky cores, thick icy mantles, and atmospheres rich in hydrogen, helium, and methane. Uranus is known for its sideways rotation and relatively calm weather, while Neptune has dynamic weather with high-speed winds and storms. Each planet has a unique ring system and several moons, with Neptune's Triton being geologically active. The video highlights the mysteries and unique features of these distant planets.
