Uranus
* Size: The third largest planet in our solar system, with a diameter roughly four times that of Earth.
* Composition: Primarily composed of hydrogen and helium, similar to Jupiter and Saturn. However, Uranus also contains a significant amount of heavier elements like ice (water, methane, and ammonia). This mixture of gases and ices gives it a pale blue-green color.
* Unique Feature: Uranus rotates on its side, with its axis tilted at almost 90 degrees to its orbital plane. This unusual tilt likely resulted from a collision with a large object early in its formation.
Neptune
* Size: Slightly smaller than Uranus, but still a giant planet with a diameter four times that of Earth.
* Composition: Also composed primarily of hydrogen and helium, with a significant amount of ices (water, methane, and ammonia). The presence of methane gives it a deep blue color.
* Unique Feature: Neptune experiences the strongest winds in our solar system, with wind speeds reaching up to 1,200 miles per hour. It also has a faint ring system.
Both Uranus and Neptune are considered "ice giants" because of their abundance of ices. They are vastly different from the gas giants, Jupiter and Saturn, which are mostly composed of hydrogen and helium with only small amounts of ice.
