The dwarf planet Pluto has four natural satellites, or moons. The largest, Charon, is more than half the size of Pluto, which could make the two a co-orbiting pair or dual planetary system. The other two named moons are Nix and Hydra. The fourth moon, discovered in 2011, has the provisional designation "S/2011P1", and is sometimes referred to unofficially as "P4."

How many reasons why Pluto is not a planet?
There are several reasons why Pluto is considered a dwarf planet rather than a full-fledged planet. Some of these include its small size, its irregular orbit, and the fact that it shares its orbit with other objects in the Kuiper Belt. Additionally, Pluto has not cleared its orbit of other debris, which is a criterion for being classified as a planet.
Why is Pluto no longer considered to be a major planet?
The word "planet" has been divided into two newer concepts: major planets and dwarf planets.The definition of major planet excludes Pluto because a major planet must have cleared its orbit of asteroids, comets, and other debris. Pluto is a part of the Kuiper belt, and has not absorbed most of the cometary bodies into itself, or captured them as satellites. Pluto is therefore a dwarf planet.The rules of a planet are:It orbits a star or the remnants of a starIt is large enough for gravity to squash it into a sphere-like shapeIt must have cleared its orbitPluto's orbit has many icy bodies in its path, most of them in the Kuiper Belt where Pluto spends most of its time.The definition of planet was changed in 2006 by the International Astronomical Union (IAU). As a dwarf planet Pluto is in the same category as Eris (which is bigger than Pluto), Ceres (king of the asteroids), and possibly other bodies being discovered in the Kuiper Belt.
Is there anything special about Pluto?
Pluto is unique in our solar system as the only dwarf planet. It has a highly elliptical orbit that brings it closer to the Sun than Neptune at times. Pluto is also known for its large moon, Charon, which is so large in comparison that they orbit each other, creating a binary system.
What massive has not Pluto to be planet?
Pluto is no longer classified as a planet because the International Astronomical Union redefined the criteria for what constitutes a planet in 2006. Pluto did not meet the new requirements, which include clearing its orbital path of debris and being gravitationally dominant in its orbit.
Why is Pluto in a class of it's own?
there are many reasons. -pluto is way smaller -pluto has a very elliptical orbit that crosses Neptune's path. -pluto has an orbit that is tilted about 17 degrees. these are only a few of the reasons. hope it helps!
How many known satellites does pluto have?
The dwarf planet Pluto has at least 10 known satellites. There is also a small system of rings of debris that has been recently detected.
How many times does the planet Pluto circle the sun in a year?
It takes 247.92 earth years for Pluto to orbit the sun once.
How many trips have people taken to Pluto?
Zero trips pluto is a gass ball that orbits neptune actually pluto is no longer in orbit and is no longer a planet
How come Pluto is not a planet no more?
Pluto is no longer considered a planet (however it is called a dwarf planet) because it failed to meet the International Astronomical Union's definition of a planet:must orbit the sun (check)nearly round in shape (also, check)has cleared its orbit area of other planets (here's where Pluto fails, as Saturn crosses Pluto's orbit every so many years)
Can the mass of a planet affect how many moons a planet has?
Yes, it can. The higher the planet's mass, the more satellites it can attract at greater distances, and the more it can keep in orbit around it.
Does its size have something to do with the reclassification of Pluto?
No. Pluto is large enough to meet the definition of a planet. It was reclassified because it does not dominate its orbit, but instead shares it with many comets.
Can the mass of a planet affect how many moons a planet ha?
Yes, it can. The higher the planet's mass, the more satellites it can attract at greater distances, and the more it can keep in orbit around it.

How many satellights are there?
There are thousands of satellites in Earth's orbit, with estimates ranging from 2,200 to over 3,000 active satellites. Additionally, there are many more inactive or defunct satellites and debris in orbit.
