The Outer planets, Uranus, pluto and Neptune documentary. This documentary focuses on the cold outer-side of our solar system and its planets.

 

Uranus

 

The seventh planet from the sun is Uranus. It was first discovered by William Herschel on march 13th 1781 using a telescope since the gas giant planet is not visible to the naked eye, interestingly it was the first planet to be discovered using such a device. Uranus rotates on its axis at 98 degrees meaning it is essentially on its side. The reason for this is most likely due to a collision with a large planet during the chaotic, early days of the solar system however scientists are not 100% sure about this yet. Despite Uranus’s rather dull appearance the planet has many interesting features to be studied including 13 rings and 27 moons, most notable of which being Miranda, Titania an Ariel. Uranus has a surface temperature of -197 degrees and an Equatorial diameter of 51,118 km making it an extremely inhospitable place and no surprise that it was only found by a telescope since it is 19.22 AU from the sun or 2,870,658,186 km. 

 

Neptune

 

Neptune is the furthest gas giant planet away from the sun and the last official planet since pluto was reduced to a proto planet. Neptune is an amazing planet to see with it’s deep blue colors brushed with white streaks, however make no mistake Neptune is a violent place with the fastest winds in the solar system estimated to exceed 2000 mph. The reason for such ferocious winds is because there is nothing to stop them unlike earth for example which has mountains and opposing global air streams. Like Saturn, Uranus, Jupiter Neptune has 5 rings of variously sized particles. Also alike the outer gas giants Neptune has a number of moons, fourteen intact, the most notable of which being triton which is the only moon in the solar system to orbit its parent planet in the opposite direction. Neptune’s surface temperature is -201 degrees Celsius, located 30.10 AU from the Sun and has and equatorial diameter of 49,528 km.
