We have reached the last planet in the Solar System, called Neptune. It is the last planet from the Sun or the eighth. Its size far exceeds that of the Earth and even if we see it a dark blue, there are other shades of blue and brown on the surface. So far Neptune is the first planet to be found through mathematics. How can this be? Alexis Bouvard noticed some disturbances of Uranus, especially in the obita, and this led him to believe that there could be an eighth planet. And in 1845, a famous mathematician named Urbain Le Verrier discovered the planet Neptune after many calculations and asked several astronomers and observers to look for it. Le Verrier and Adams contributed to the discovery of the planet, and when it was discovered, it was at 1 ° distance from Le Verrier's prediction and at 12 ° distance from Adams, that is, the two were right, with almost exact path. . Neptune also has rings, even if they are difficult to see. The inclination of Neptune's axis of rotation is 28.32 °, which is not very large and is similar to the Earth which has an inclination of 23 °. Neptune's gravity has a huge impact on the Kuiper belt, which is near Neptune, in time, Neptune's orbit has disrupted some phenomena in the Kuiper belt, so Neptune dominating the Kuiper belt. Neptune is very far away and there is not much chance of reaching it, but it is a beautiful and mysterious planet, like Uranus, because it is still waiting to be discovered.
