No. Planet X was a proposed planet believed to orbit somewhere beyond Neptune based on an anomaly in the orbit of Uranus believed to be caused by the gravity of an unknown planet. Searches for planet X led to the discovery of Pluto, but later studies found that Pluto is not nearly massive enough to have caused the anomaly. It was later discovered that the apparent anomaly was due to a small miscalculation in the mass of Neptune.
No. An exoplanet is a planet that orbits a star other than our sun. Pluto orbits our sun.
Pluto is not referred to as Planet X. Planet X is a term used for an unknown theoretical planet at the edge of the solar system.
Niburu x has been said to have existed after planet pluto disintegrated
Percival Lowell calculated Planet X's approximate location before his death in 1916. Today, Planet X is referred to as "Pluto".
Pluto is not a planet
Planet X is the theorized, but unconfirmed, "10th" planet in our solar system (when we had 9 planets total and Pluto was still considered a true planet). This elusive "Planet X" was thought most likely to be a gas giant and probably the cause of Pluto's off-planar orbital tilt. It was also thought to be the cause for some strange behavior with Neptune in respect to the other gas giants. In fact hunting for "Planet 9" was why Pluto was discovered in the first place. It soon became apparent, however, that Pluto was not "massive" enough to have caused the anomalies with Neptune - hence the hunt for Planet X.
Pluto is not a planet, but it is a dog from Mickey Mouse. Pluto, is rather a dwarf planet, because it is not big enough to be a planet.
"Planet X" was originally a term for a hypothetical TENTH planet, BEYOND Pluto. Also, Pluto is no longer considered a planet.
yes there is a planet beyoned Pluto it is called the planet x
planet x is unknown but is farther than Pluto
though it is not a planet anymore no planet X is.
Planet x is the planet behind Pluto which is commonly reffered to as Selena but is not yet a planet(or clarified planet).
Niburu x has been said to have existed after planet pluto disintegrated
all i know that planet x is past Pluto
Pluto or that planet X found a few years ago
They wanted a Roman or Greek God Name for the new "Planet". PL honored the astronomer who discovered that Pluto should exist.
Generally, Planet X is an undiscovered planet in our solar system. Pluto was "Planet X" until it's discovery in 1930. Scientists postulate the existence of a Planet X by noting irregularities in the orbits of other planets. Now, Pluto and anything past it discovered so far are known as dwarf planets. There maybe another planet somewhere past Pluto, but I believe Planet X now refers to extra-solar planets.
There are many, including Planet X.
Pluto, it is now a dwarf planet or planetoid.
