The Double Sunrise was created in 1943.
Mercury has a double sunrise because when the sun rises a bit, an orbital effect makes it sink down and rise again.
Since every planet has some degree of tilt between its axis of rotation and its orbital plane, every planet has latitudes along which sunset is immediately after sunrise around the days of that planet's solstices.
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.
First of all, Pluto is not a planet. It was considered a double planet because its largest moon Charon is half its size.
Live on the Double Planet was created in 1986-07.
Some consider it to be a double planet or, more properly, a double dwarf planet. However it is currently not officially considered as such.

Within our own solar system, some view Pluto as being a double planet with it's moon Charon (which is half it's size).
Both Mars and Venus are visible in the East before sunrise. Venus is brighter, and more white colored; Mars is higher, a little dimmer, and distinctly reddish.
