Neptune
Neptune is the eighth planet from the Sun. It is the third largest planet with respect to mass, and the fourth largest in terms of diameter. Neptune was named after the Roman god of the Sea because of its Blue color.
Some Amazing Facts About Neptune:
1. Year And Day
Neptune takes 164.8 Earth years to orbit the Sun. It means Neptune completed its first full orbit on 11 July 2011 since its discovery in 1846.
Neptune take 18 hours to complete one rotation which is noticed via it's equatorial clouds.
2.Temperature
Neptune is the second coldest planet after Uranus in our Solar System. It has an average surface temperature of -214°C (approximately -353°F).
3.Atmosphere
Neptune’s upper atmosphere is composed of 80% hydrogen (H2), 19% helium and trace amounts of methane. The traces of methane absorbs red light, which makes the planet appear a lovely blue.
4.Spacecraft Mission
Only one spacecraft, the Voyager 2 spacecraft swept past the planet in 1989.It sent the first close-up images of the Neptune system.
5.Rings
Neptune has also a ring system but very faint and thin. They are most likely made up of ice particles and grains of dust with a carbon-based substance coating them.
6.Moon
Neptune has 14 known moons in which Triton is the largest moon.Triton is a frozen world which spits out particles of nitrogen ice and dust from below its surface.
7. Active Climate
The climate on Neptune is extremely active.In its upper atmosphere,Large storms whirl with high speed wing up to 600 meters per second.The largest storm was the Great Dark Spot in 1989 which lasted for around five years.
