They call Pluto the double planet because rather than Charon simply orbiting Pluto, the two objects revolve around their common center of mass, which lies outside of Pluto.
First of all, Pluto is not a planet. It was considered a double planet because its largest moon Charon is half its size.
That's easy its pluto
There are no double planet systems in our solar system. The closest to being considered a double planet are Pluto and its largest moon Charon, but since Charon is significantly smaller than Pluto, it is not classified as a double planet system.
No, because Pluto has been reclassified as a dwarf planet. Dwarf planets are not planets, despite the confusing term. Before Pluto was reclassified as a dwarf planet, sometimes the Pluto-Charon system was thought of as a double planet, so you can sometimes find that in outdated but authoritative-seeming references.
yes
Charon. It's more of a satellite than a planet, unless you want to consider Pluto/Charon as a double planet. That's a little awkward, since Pluto has been downgraded to a planetoid.
None. Pluto-Charon was almost considered one in 2006, though that would be a dwarf double planet rather than a true double planet as Pluto is not a planet. In billions of years the Earth and Moon will be a double planet. Also, the question is non-sensical because if it was a double planet then they would both be planets... so there would be no moon. A planet would be considered a double planet with it's opposite planet, not moon.
Some consider it to be a double planet or, more properly, a double dwarf planet. However it is currently not officially considered as such.
It is still known as Pluto, even though it was downgraded to a dwarf planet and given a number. So really we should call it 134340Pluto.
Pluto, it is now a dwarf planet or planetoid.
Pluto was named after the planet, Pluto, which had been discovered by the time his character was created.
No.It is a satellite (moon) of Pluto, which itself was declared a "Dwarf Planet" at the International Astronomical Union (IAU) Symposium in 2006.Pluto is very small - only 2/3rds the size of Earth's moon. Charon is 1/2 that size - which is large enough that the IAU would have faced calling Pluto-Charon a "Double Planet" if they had decided to call Pluto one.However, IAU's decision was based upon the fact that there are MANY objects in similar orbits to Pluto's (some even larger than Pluto itself, such as Eris), and we would have ended up listing dozens (possibly hundreds) of objects as "Planets"No. Charon is not a planet; it is a moon of the dwarf planet Pluto.
