Detailed explanation-1: -Titan has liquid seas made of hydrocarbon, lakes, mountains, fog, underground water oceans and yes, it does rain methane on Titan. In fact, Earth and Titan are the only worlds in the Solar System where liquid rains on a solid surface-through again, the rain is methane and not water.

Detailed explanation-2: -Our home planet is the third planet from the Sun, and the only place we know of so far that’s inhabited by living things. While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface.

Detailed explanation-3: -Jupiter has become known for its helium rain, and ammonia “mushball” hail and methane rain down on Titan. Steady rains of tiny, glittering diamonds may fall on Neptune. On planets outside of our solar system, known as exoplanets, scientists believe it only gets weirder.

Detailed explanation-4: -What causes rain? Clouds are made of water droplets. Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain.

Detailed explanation-5: -On Venus, it rains sulfuric acid. On Mars it snows dry ice, which is carbon dioxide in a solid state. Saturn’s moon Titan rains methane, and on Jupiter, it rains helium and mushy ammonia hailstones. On Neptune, scientists suspect it rains pure carbon in the form of diamonds.
