Pluto was considered the farthest planet until September 13th, 2006 when it was reclassified as a dwarf planet. But the correct answer would be neptune -goober;P
The planet that was farthest from the Sun from February 7, 1979 until February 11, 1999 was Uranus. Though Pluto was considered the outermost planet in the solar system since its discovery, its highly elliptical orbit sometimes brought it closer to the Sun than Uranus.
Pluto used to be the outermost planet, except that sometimes it became Neptune because Pluto's elliptical orbit is far from circular. From 1979 to 1999 Neptune was the farthest planet from the Sun and remains the farthest from the Sun today, because Pluto us no longer defined as a planet.
In 1999 Pluto was considered to be a planet. From 1979 to 1999, Neptune was further from the Sun than Pluto, because of Pluto's eccentric orbit.
2300 Km in its outermost ringed structures (Smith etal, 1999. Science)
Neptune, the farthest planet away from earth in our solar system is 4.3 billion kilometers from earth. The planet OGLE-05-390L b orbits a star about 6000 parsecs... about 20000 light years from earth. They're finding planets around other stars almost weekly... So that may change. The farthest (galaxy) we know of is a quasar whose light has been traveling for 12 billion years. That object is now about 27 billion light years from us. Since the universe is about 15 billion years old... That's as far as we can see back in time. The light from anything much further away wouldn't have had time to get to us.
In our solar system the outermost planet 'til March 1999 was considered the same as the outermost planet after March 1999 - it was Pluto. In 2006, the IAU reclassified Pluto as a minor or dwarf planet and no longer a true planet - this demotion meaning Neptune would thereafter be considered the outermost planet in our solar system. It is of course possible there is a planet out there not yet discovered, which is in solar orbit, and large enough, in which case its distance might qualify it as 'outermost'.

Neptune.
Neptune
On February 11th, 1999, Pluto became further from the Sun than Neptune again. However, the IAU does not regard it as a planet any more.
Mercury has always been the closest planet to the Sun and unless a little rogue planet slipped in between, during 1999, then Mercury is still the closest to the Sun
Pluto's orbit had finished it cut throught Neptune's Orbit.
it used to vary between neptune and Pluto due to plutos unusual orbit. but since Pluto was declared not a planet. it is neptune.
