Today’s source of Inspiration is exploration and knowledge gained through exploration. Our universe is filled with places to explore and much to learn. Neptune is the eighth planet from our Sun.
Neptune is, also, a blue colored planet. Neptune is an ice giant. It is the fourth-largest in diameter and the third-most dense planet. It has 17 times the mass of Earth. Neptune takes almost 165 years to revolve around the Sun. The axial tilt is similar to Earth’s, so it does experience seasons. Neptune has a differential rotation and from the equator to the planet’s magnetic field the rate of rotation varies from 18 hours to just over 16 hours.
Neptune cannot be seen by the naked eye. It was found by mathematical prediction. Several people were involved in the discovery of Neptune and claim of its discovery has been fought over. The year that it was discovered is 1846. Urbain Le Verrier is credited with naming Neptune, if not credited by everyone as the only person to discover the planet. There was a struggle and stories surrounding naming it as well.
Neptune experiences extremely dynamic storm systems. The Great Dark Spot was observed in 1989 and is an anti-cyclonic storm system. In 1994 the Hubble Space Telescope did not find the Great Dark Spot, but found a similar storm spot in Neptune’s northern hemisphere.
The internal structures of Neptune and Uranus are believed to be similar. The upper atmosphere is followed by an atmosphere layer consisting of hydrogen, helium, and methane gas. Next, the mantle contains water, ammonia, and methane ices. Finally, is the core with rock, silicates and nickel-iron.
Neptune has a ring system with arcs. There are 14 known moons orbiting the planet. Triton is the largest moon and the coldest known object in the Solar System. Voyager 2 is currently the only spacecraft to have visited Neptune. More missions are planned. We continue to learn. Be inspired! Have a bright day!
