interesting facts about neptune
Hi Guyz Again! This is SOUMYA!! In this article, I’ll talk about interesting NEPTUNE facts, weird/cool information about NEPTUNE,, and lots of random facts about NEPTUNE. Yes, it’s all about NEPTUNE here.So WHY Wait? Let's get it STATR!
The only spacecraft that has ever visited Neptune was NASA’s Voyager 2 spacecraft, which visited the planet during its Grand Tour of the Solar System. Voyager 2 made its Neptune flyby on August 25, 1989, passing within 3,000 km of the planet’s north pole. This was the closest approach to any object that Voyager 2 made since it was launched from Earth.
At the top of its clouds, temperatures on Neptune can dip down to 51.7 Kelvin, or -221.45 degrees Celsius (-366.6 °F). That’s almost three times the coldest temperature ever recorded here on Earth (-89.2°C; -129°F), which means that an unprotected human being would flash freeze in a second! Pluto gets colder, experiencing temperatures as low as 33 K (-240 °C/-400 °F).
Think a hurricane is scary? Imagine a hurricane with winds that go up to 2,100 km/hour. As you can probably imagine, scientists are puzzled how an icy cold planet like Neptune can get its cloud tops t0 move so fast. One idea is that the cold temperatures and the flow of fluid gasses in the planet’s atmosphere might reduce friction to the point that it’s easy to generate winds that move so quickly.
6. The Discovery of Neptune is Still a Controversy:
The first person to have seen Neptune was likely Galileo, who marked it as a star in one of his drawings. However, since he did not identify it as a planet, he is not credited with the discovery. That credit goes to French mathematician Urbain Le Verrier and the English mathematician John Couch Adams, both of whom predicted that a new planet – known as Planet X – would be discovered in a specific region of the sky.
Neptune is a ball of gas and ice, probably with a rocky core. There’s no way you could actually stand on the surface of Neptune without just sinking in. However, if you could stand on the surface of Neptune, you would notice something amazing. The force of gravity pulling you down is almost exactly the same as the force of gravity you feel walking here on Earth.
