To go to it. ;)
Neptune is the furthest official planet, however chronos is the furthest discovered dwarf planet.
No one is has not been discovered yet.
a) Earth is not a star, but a planet. b) Earth is not part of "another galaxy", but of our own galaxy.

yes Mars
The galaxy is not a planet. The galaxy is MADE of millions and millions of stars and planets.
it depends whether how far or close it is for example the new planet discovered on sept. 29, 2010 which is next door to us in another galaxy, would take at least 200 to get there. no one person could live that long
The first extra-solar planet (in other words, circling a star and not our sun) was discovered in 1995.
by crazy monsters that came to this planet from Minos at another galaxy
Kepler 22-b is a planet. It is located in our Milky Way galaxy - like most planets discovered so far. Any planet outside of our Milky Way would be extremely hard to detect.

After Neptune was discovered, they were claims that its orbit didn't seem to be as predicted. This led to the conclusion that it must be disturbed by another massive planet beyond it. Later Pluto was discovered, but it's mass was not large enough to disturb Neptune. For many years astronomers searched for another planet, but it was recently discovered that Neptune's orbit is not as perturbed as once thought, so the "need" for another planet is gone.
