Neptune
Venus
Netune
Kepler discovered that the orbit of each planet is an ellipse rather than a perfect circle. The planet with an orbit that is closest to a circle is Venus.
False. A moon, by definition, orbits a planet.
Neptune (the eighth and outermost planet) was discovered on September 23, 1846. It takes 164.79 Earth years to complete one orbit and will therefore only complete its first orbit since its discovery in 2011. It is also worth noting that while Pluto is not longer regarded as a planet (it is now a minor planet) it was discovered in 1930 and takes 248.09 Earth years to complete an orbit.
Jupiter, it has 63 confirmed that are in a stable orbit around the planet. There could well be more than this though, which have yet to be discovered.
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.
He discovered that avery planet has a ellipcial orbit, which means oval.
Uranus is the planet that was discovered beyond the orbit of Saturn. It was discovered on March 13, 1781 by William Herschel.
Kepler discovered that the orbit of each planet is an ellipse rather than a perfect circle. The planet with an orbit that is closest to a circle is Venus.
Ellipse.

Each planet is in its own orbit and obey's Kepler's laws of planetary motion. Newton later discovered that the Sun's gravity is what makes the planets move in their orbits in the way they do.
The moon Miranda orbits the planet Uranus and it was discovered in 1948. Uranus has a total of five moons.
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.
the reason Neptune is the planet discovered by pen is because unlike the other planets, Neptune was not discovered by finding it in the night sky. After Uranus was discovered, it was seen that its orbit was different than what was predicted, and it was decided that this was because of another unknown planet's gravitational pull. Then, mathematics was used to find the other planet, Neptune.
