Stormy Methane Weather
The fastest winds in the solar system propel huge storms through Neptune’s frigid deep-blue methane atmosphere.
Gravity’s Relentless Force
Gravity holds the solar system together. The Sun, which has the strongest gravita-tional pull, keeps all the planets, asteroids, and comets in orbit. In turn, planets tug on one another and their moons. Neptune was discovered when astronomers noticed that something was disturbing the orbit of Uranus (diagram left). The moon Triton (smaller object below) was captured by Neptune’s gravitational pull and diverted into orbit around the planet.
