Pluto and Charon are the closest bodies in our solar system to an answer to this question, however, neither is a planet. Pluto used to be, but times change. When Pluto was a planet, it and its moon, Charon, were the closest in size of any of the planets. Currently the planet and moon with that distinction is the earth and its moon, the Moon. But no two bodies within our solar system which are classified as planets are considered double.

Why are there eight planets in the solar system?
There were nine planets. Then astronomers got together and decided what to do with Eris, a dwarf planet that was discovered. They decided to make a definition for what is a planet. That led to Pluto being demoted to a dwarf planet.
Can double stars have planets?
It is possible but a planet in a binary star system would have a complex orbit that might not be very stable in the long term, so there is a chance of it being swallowed up by one of the stars.
How does Pluto not being a planet affect us as people?
The simple answer is that it doesn't! It will change what kids learn in school about the solar system but that's about it. For the scientists and astronomers it means they will need to take into account the definition of 'planet' and 'dwarf planet' when classifying new planets in the future or even reclassifying current planets/dwarf planets... Hope that helped :)
Is a dwarf planet the same as a moon?
no. a dwarf planet is a planet that doesnt have the characteristics for being a planet so its counted as a planet, a dwarf planet can have moons, such as Pluto has 3 moons, but a moon cant have a moon, so therefore dwarf planets and moons are diffrent.
Why do the inferior planets go into retrograde only at inferior conjuction?
I believe it has to do because Earth passes up inferior planets while the planets are in inferior conjunction. The only way retrograde works is if the earth is passing a planet. While a inferior planet is in superior conjunction it is not being passed up.
Is the coldest planet Uranus or Neptune?

Is the sun closer to earth than a planet?
There are 2 planets that are closer to the Sun than Earth, the planets obviously being Mercury and Venus.
Why asteroid is said to be a planet?
A planet used to be defined as an object that orbits the Sun. Asteroids orbit the Sun, so are planets. Recently The definition of Planet has been revised so that they are not considered planets any more. (The redefinition has lead to Pluto no-longer being a planet too.)
How many Dwarf planet are in your solar system?
There are currently 5 dwarf planets that are being recognized.

Why was Pluto eliminated from the planet list?
It was regarded by scientists as being "too small" to be classed as a planet. So they put it into the category of Dwarf Planets.
Which is the planet is called double planet?
Within our own solar system, some view Pluto as being a double planet with it's moon Charon (which is half it's size).
