False. A moon, by definition, orbits a planet.

Kepler discovered that the orbit of each planet is an what rather than a perfect circle?
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.
Which planet was discovered when a neighbouring planet strayed from its orbit?
Neptune
How far is planet x from the sun?
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.
Which planet has not completed an orbit around the sun since its discovery?
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.
What planet is most circular orbit of any of the planets?
Probably Venus, who's orbit varies only imperceptibly from a perfect circle. Venus's orbit is elliptical, but not so the average layman would notice (to astronomers, of course, it is quite different).
Explain about planet X?
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.
In the 1800s why did astronomers predict that the planet neptune would be discovered well before anyone had seen it?
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.
Astronomers discovered a moon that does not orbit a planet?
that would ruin the very definition of a moon. a moon is an object that orbits a planet, so it's impossible.
What do hydra and nix do for Pluto?
These are two additional moons of Pluto, that were recently discovered in orbit around the Dwarf Planet.
Kepler discovered that the orbit of each other planet is?
He discovered that avery planet has a ellipcial orbit, which means oval.
Was Neptune accidentally discovered?
No. The existence of Neptune was predicted based on the slight disturbance of its gravity on the orbit of Uranus. Astronomers then searched for this then-unknown planet.
What planet was discovered beyond the orbit Saturn in 1781?
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 what rather than a perfect circle?
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.
Why do you say that Neptune the planet was discovered by pen?
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."
Kepler discovered that the orbit of each planet is a?
Ellipse.
Which planet was found by accident?
All planets in our solar system were found intentionally. Mercury, Venus, Mars, Jupiter and Saturn were known since ancient times. Uranus was thought to be a star by early astronomers until William Herschel discovered it was in orbit with the sun. Neptune was also thought to be a star by Galileo and was discovered to be a planet by the calculations of deviations in the orbit of Uranus mid 19th century. Similarly, Pluto (which has lost its planet hood status since 2006) was discovered intentionally however by false calculations in the orbit of Neptune.
Which planet was discovered when a neighbouring planet strayed from its orbit?
Neptune
