Important Kid facts about Neptune.
- Discovery of Neptune: Planet Neptune was found in 1846 by Jean Le Verrier. Neptune was discovered later than all of other planets since it was not visible to naked eyes and was not known to the ancients.
- Named after Roman god of the sea: This is the because of its blue ocean like color.
- Neptune was called Le Verrier before: This name is of the man who discovered the Neptune and this name didn’t stick for the long time. Later the name was renamed it as a Neptune to fall in the line with all other planets named after Roman Gods.
- Discovered by watching the orbit of Uranus: Planet Neptune was discovered when the orbit of Uranus is observed. It was seen that planet Uranus was being pulled from its orbit by a gravitational force at the same point each time it went around the Sun. So further observations led scientists to find Neptune.
- Takes 164.8 earth years for one rotation: Neptune takes 164.8 earth years to orbit the Sun, which is of 60190 Earth days. After discovery of Neptune in 1846 its first journey was completed in 2011.
- One of the Gas giants: Neptune’s has the layers 80% hydrogen, 29%helium and methane gas. Planet Neptune doesn’t have a solid surface but it is similar to the size of Earth.
- Also called an Ice Giant: Like Uranus planet Neptune is also called as Ice giants because it consists of inner layer of ammonia, water and methane ice.
- Has Dark spot storm: Neptune has a Great Dark Spot Storm which is similar to the Great Red spot on Jupiter. The storm is about the same size as planet Earth.
- Spins quickly on its axis: Planet Neptune, although it is slow to move around the sun but it spins quickly on its axis. A day on Neptune is 18 hours which is six hours less than Earth takes to rotate.
- Neptune’s Moons: Planet Neptune has 14 moons, the biggest one is called Triton which was discovered a number months after the discovery of Neptune. Triton is a special moon as it orbits Neptune’s but turns the reverse direction on its axis. It means they are spinning in reverse directions. Imagine walking around an object like a car (the Sun) whilst spinning around clockwise (Neptune) with a friend walking around you in an anti-clockwise circle (Triton).
- Neptune is extremely cold:The planet has an average temperature of -214 degrees Celsius (-353 degrees Fahrenheit) The temperature stays low most of the time because it is so far away from the sun.
- Neptune has strong magnetic field: Planet Neptune is around 27 times stronger than the one on Earth. It is special when it is compared with other planets because it is not in line with the planet’s axis and so is tipped on its side at 47 degree angle.
