Neptune

Neptune, the eighth and farthest planet from the Sun, is a deep blue ice giant. Its atmosphere is incredibly dynamic, with the fastest winds in the Solar System. Neptune’s largest moon, Triton, has geysers that erupt nitrogen gas, and it orbits the planet in the opposite direction of its rotation.

Formation and Structure of Neptune

Neptune, the farthest planet, formed in the outer Solar System from gas and icy materials. Its structure includes:

• Core: Small, rocky, and dense.
• Mantle: A mix of water, ammonia, and methane.
• Atmoshpere: Dynamic, with hydrogen, helium, and methane.

Significance

Neptune’s weather systems and Triton’s retrograde orbit provide valuable data on the Solar System’s dynamics.

Fun Facts

• A year on Neptune lasts 165 Earth years.
• It was the first planet discovered through mathematical predictions rather than direct observation.
