False. A moon, by definition, orbits a planet.
Neptune was discovered when astronomers noticed that the orbit of Uranus was being perturbed by gravitational forces from an unknown distant planet. This led to the search for and eventual discovery of Neptune in 1846.
Neptune was discovered in 1846 through observations of Uranus. Uranus' orbit was seen to appear to alter slightly through the gravitational effect of another planet, which turned out to be Neptune.
Planet X is a hypothetical planet once thought to exist out beyond Neptune. Astronomers discovered a discrepancy in Uranus' orbit that they thought indicated another planet beyond Neptune whose mass was affecting it. When Neptune's mass was determined using data gathered by Voyager 2, Astronomers discovered that the discrepancy was entirely due to Neptune's orbit. Since then, other trans-Neptunian objects have been discovered, but none large enough to be considered a planet.
Neptune. Because of the accidental discovery of Uranus, it was calculated that a larger body had to have been disrupting it's orbit. A comet, asteroid and star were ruled out as the cause of a disruption because they were incapable of staying in such a regular motion around the sun. Therefore the body had to be a planet. Using the obervational information from Uranus' disruptions it was calculated where Neptune should be at any one time.
Neptune was discovered because of anomalies in the orbit of Uranus, indicating that another planet's gravitational pull was affecting Uranus's orbit. This led to the prediction and eventual discovery of Neptune in 1846 by Urbain Le Verrier and John Couch Adams.
After Neptune was discovered, they were claims that its orbit didn't seem to be as predicted. This led to the conclusion that it must be disturbed by another massive planet beyond it. Later Pluto was discovered, but it's mass was not large enough to disturb Neptune. For many years astronomers searched for another planet, but it was recently discovered that Neptune's orbit is not as perturbed as once thought, so the "need" for another planet is gone.

Astronomers saw some deviations from the expect orbit of the planet Uranus. Based on these deviations, some theorized that Uranus was being pulled out of its expect orbit by another planet, which turned out be Neptune.
These are two additional moons of Pluto, that were recently discovered in orbit around the Dwarf Planet.
He discovered that avery planet has a ellipcial orbit, which means oval.
Uranus was observed deviating from its predicted orbit, leading astronomers to hypothesize the existence of an unseen planet exerting gravitational influence. This discrepancy prompted the search for Neptune, which was later discovered in 1846.
Yes, Neptune was accidentally discovered. In 1846, astronomers noticed small positional discrepancies in the orbit of Uranus, which led them to predict the existence of another planet influencing its orbit. Independently, both Urbain Le Verrier and John Couch Adams calculated the position of this new planet, leading to the discovery of Neptune.
A moon that does not orbit a planet is called a "moonmoon" or "submoon." It would directly orbit a larger moon, which in turn orbits a planet. This scenario is theoretically possible but has not been observed in reality yet.
Uranus is the planet that was discovered beyond the orbit of Saturn. It was discovered on March 13, 1781 by William Herschel.
Neptune was discovered in 1846 through observations of Uranus. Uranus' orbit was seen to appear to alter slightly through the gravitational effect of another planet, which turned out to be Neptune.
It's a long story, and to answer it, we have to go all the way back to when Uranus, the planet before Neptune, was discovered. Uranus was discovered in 1781, and astronomers started calculating the orbit it should be following around the Sun. However, within a few years, astronomers started noticing the planet wasn't quite following the orbit they'd assigned it; it was slightly out of place. No matter how hard they tried, the mathematicians couldn't manage to calculate an orbit for Uranus that fit the facts. In 1845, two astronomers, John Couch Adams in England and Urbain LeVerrier in France, working independently of each other, came to the conclusion that there must be another planet beyond Uranus, pulling on it with its gravity and affecting its orbit. They used the discrepancies in Uranus' orbit to calculate where the new planet should be, but couldn't get anyone interested for a long time. It wasn't until 1846 that a German astronomer, Johann Gottfried Galle, using LeVerrier's calculations, decided to look at the spot in the sky LeVerrier had predicted the planet should be - and lo and behold, there was Neptune! So Neptune was discovered by Adams and LeVerrier, writing down their calculations with a pen, before astronomers had ever actually seen it. That's why Neptune was "discovered by pen."
Ellipse.
