īecause all other planets are named after deities, Friedrich Struve liked the name Neptune, as originally proposed by Le Verrier, which is the god of sea in Roman mythology. Le Verrier originally suggested the name Neptune, but later changed it to ' Leverrier' after himself, but non-French people hated the name. Instead, Challis suggested the name ' Oceanus'. The first name suggestion was the name ' Janus'. NamingĪfter the discovery, people called Neptune "Le Verrier's planet" and "planet beyond Uranus". However, in 1998, historians decided Le Verrier deserved more credit than Adams because Le Verrier's prediction was more accurate. Later, people agreed that both Le Verrier and John Adams deserved credits. Since humans like credits and arguing, many arguing happened between the Brits and French about who should deserve the credit for the discovery. James Challis realized he already has observed this planet twice, but he didn't recognize it because he was careless. With this, he can see the change in the position of the planet, and when Johann Galle looked at the position, there it was - a planet. Le Verrier also told Johann Galle to find the planet.Ī student from Berlin, Heinrich d'Arrest, drew a new map of the sky in the area where Le Verrier predicted the planet to be and compared it with the actual sky. After a few months, he finally began his planet-finding job. He told James Challis to find the planet, but Challis decided to procrastinate. The following year, John Herschel supported Le Verrier's calculation. In 1845, Urbain Le Verrier made his own calculation, but he failed to get attention from other astronomers. 22 years later, John Adams calculated that this body might be another planet. So, Bouvard deduced that an unknown body was causing this weird motion due to its gravity. Astronomers, including Bouvard, observed Uranus had a weirder orbit than they expected. In 1821, the French astronomer Alexis Bouvard published astronomical papers of Uranus' orbit. However, Galileo wasn't credited for this drawing because he thought it was a star. His drawings showed a star next to Jupiter, and scientists think the star was actually Neptune. The first known possible observation of Neptune was by Galileo Galilei on December 28, 1612. It was probably a dwarf planet in the Kuiper belt before it was captured by Neptune. It is the largest and the only spheroid-shaped moon that is irregular and has a retrograde orbit. It is the last planet to be discovered in the Solar System.Īs of September 2021, scientists have discovered 14 natural satellites in orbit around Neptune. It is named after the Roman god of the sea, 'Neptune'. It is the only planet in our Solar System that can't be seen with the naked eye. ĭue to its distance, which is 30 times the distance between Earth to the Sun, Neptune is not visible to the naked eye. This is probably because it is massive, so its gravity is stronger, which compresses the planet. At a diameter of around 50,000 km, it is the fourth-largest planet in the Solar System and the smallest of giant planets. It is one of two ice giants in the Solar System along with Uranus. Neptune is the eighth and the last planet from the Sun.
