The Planet Neptune is in the eighth positioned planet from the Sun. This planet is faster than the sound speed and is renowned for strong winds. Neptune is far out and really cold. This planet is far from the sun to over 30 times as the earth. It features a rocky core. This was the first planet forecasted as existed using math, even before it was discovered. Neptune is 17 times massive as Earth.
- Orbit: 165 earth years
- Diameter: 30,775 miles (49,530 km)
- Day: 19 earth hours
Neptune, the eighth planet was predicted on Sept 23, 1846, even prior to seeing it through a telescope. Galileo, the previous astronomer mistook this planet to be a star owing to its slow motion. Neptune acquired the name as the Roman god of the sea. However, Johann Galle based on calculations spotted Neptune through a telescope.
Neptune has a blue tint owing to an unidentified compound and absorption of methane red light in the planets due to the hydrogen-helium atmosphere. Neptune is dubbed often as ice giant as it possesses a slushy mix of thick water, methane ices and ammonia in its atmosphere and is 17 times earth’s mass and the volume is nearly 58 times as per NASA. The rocky core of Neptune is equal to Earths mass.
Neptune winds reach 1500 mph and are detected to be the fastest in the solar system. It receives sunlight to maintain warmth though it is at the farthest distance from the sun. This oval shaped ‘Great Dark Spot’ spinning counterclockwise was huge to contain entire earth and moves nearly 750mph westward.
Magnetic poles of the planet Neptune are tipped more than 47 degrees in comparison to others that spins together. As such, the magnetic field of this planet is nearly 27 times powerful than the earth’s and with each rotation it undergoes wild swings. Considering the cloud formations, scientists calculated that it takes less than 16 hours to complete a day.
Neptune’s oval-shaped orbit is at a distance of (4.5 billion kilometres) 2.8 billion miles, from the sun. It is 30 times roughly away from the Earth such that it cannot be seen through the naked eye. Neptune goes roughly every 165 earth years around the sun.
Every 248 years, Pluto appears to move closer to the sun and this is because it moves inside the orbit of Neptune for 20 years. Nevertheless, Neptune is the farthest planet and Pluto was considered as a dwarf planet.
