\n

Neptune is an icy giant planet<\/strong>, composed mainly of gas and ice. Its blue colour comes from the methane in its atmosphere. It has a tilt similar to that of Earth, allowing it to experience seasonal cycles during its revolution\u2014although on Neptune, each season lasts more than 40 years (CNES). Its name comes from the Roman god of the oceans, Neptune (known as Poseidon in Greek mythology).<\/p>\n<\/div><\/div>

Eighth planet from the Sun, Neptune follows the same general principles of formation as the other gas giants.<\/strong><\/p>\n<\/div>\n\n

\n

The creation of Neptune dates back to the formation of the solar system, around 4.5 billion years ago. According to the widely accepted theory, Neptune formed from a disk of gas and dust surrounding the young Sun, known as the solar nebula. Here is an overview of Neptune\u2019s formation process:<\/p>\n<\/div>\n\n

\n

Formation of the protoplanetary disk:<\/strong> At the beginning of the solar system’s formation, a vast amount of gas and dust began to collapse under its own gravity, forming a protoplanetary disk around the young Sun.<\/p>\n<\/div>\n\n
