What is the fardest planet in the solar system this 21st century?

Xena is the furthest, with a distance of 97 astronomical units from the sun

Pluto is the 9th farthest planet form the sun. Sometimes it becomes the 8th farthest planet. Once in every 248 years for 20 yrs.\n\npluto is considered by some to not be a planet at all.  If u want i will tell u the reasons

Abell 1835 IR1916 is the furthest galaxy that humans have found so far. It is 13.2 billion light-years away.

At 09:38am EDT on May 15, 2006, the planets were not aligned, not even close--the planets were all over the sky.\n\nIn order along the ecliptic, starting with Aires (where the sun is) and going around through Pisces, etc. we have:\n\nMercury, Venus, Uranus, Neptune, Pluto, Jupiter, Saturn, Mars\n\nSaturn and Mars were about 17 degrees apart, but everything else was even farther apart.  Saturn and Jupiter were farthest apart, at 96 degrees.

Yes. It's actually in our own solar system.  Whether it is a planet or not is the real question.  It is really small.  While bigger than pluto, it is still smaller than the Earth's moon!

Pluto is the fartherest planet, there is some discussion about it being a planet or not but for this answer we'll let it be one, from the sun during most of it's orbit. It's 5,913,520,000Km from the Sun.\nThe Main asteriod belt lies between Mars and Jupiter, roughly 374,172,480Km from the sun, the planets run Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune & Pluto.\nThe Kuiper Belt, made up of comets instead of asteriods, lies outside of the orbit of Pluto and some think Pluto is just a comet from this belt. Then going way on out past the Kuiper Belt you run into the Oort Cloud roughly 22,450,348,800,000Km from the Sun and made up of trillions of cometary bodies.

defintly pluto because you would go passed all the other planets to get there and maybe you could even find a new one.

UB313, the 10th "planet" that is said to be bigger than Pluto.\n\nI'm not lying, read all the sources.\nBTW, the CNN news which adds support to the discovered planet is dated February 2, 2006.

It's the biggest planet in our solar system.1300 times larger than earth.It has a storm that has been raging for over 300 years in it's atmosphere called the Great Red Spot.It's also the storm that torn Comet Shoemaker Levy 9 to pieces.One of it's crust layers consists of liquid metallic hydrogen.

There are ten planets in our solar system namely mercury,venus,earth mars,jupiter,saturn,uranus,neptune,pluto\nand\n2003-UB313 is the official name of the object that is considered to be a contender for the title of "10th planet". As of August 1st, 2005 the IAU has yet to confirm whether this object will be officially be recognized as the 10th planet in our solar system. This little page will follow events and provide more information when available.\nOfficial Name:  2003 UB313  \nProposed Name:  Unknown\nThe name Xena is rumored to be the name submitted to the IAU for approval, althought there is no official confirmation of the name. "..that was our tongue-in-cheek internal name, never intended for public consumption," says Professor Brown \nDiscovered By: Michael Brown, professor of planetary astronomy at California Institute of Technology (Caltech) and colleagues Chad Trujillo of the Gemini Observatory and David Rabinowitz of Yale University.\n\nFirst photographed in 2003 using a 122cm telescope at the Palomar Observatory. \n \nEstimated Size:  approx 2700 km (1,700 miles) in diameter\nThis is the estimate as of August, 2005. From Wikipedia - Although the object's diameter is not yet well determined, it is estimated to be between 2,390 and 3,550  km . The amount of light it reflects (its albedo ) seems to be quite high, and initial observations show that methane ice is present on the object's surface. Both these properties make it more similar to Pluto than previously discovered large outer solar system planetoids .  \nOrbit: 560 years \nestimated one solar orbit per 560 years.  \nDistance from Sun:\n approx 9 billion miles / 14.4 billion km\nThis is around 100 times the Earth's distance, or 3 times Pluto's distance from the Sun. \nWhere is it Now?  At present, it is near its farthest point from Earth, but in about 280 years, it will be as close as Neptune, (the eighth planet, discovered in 1846).

Of the 4 you present, Saturn, the furthest from the sun, appears to move slowest ON AVERAGE.  This ignores the fact that Mercury appears to stop entirely twice in its orbit since we're looking at it from outside its entire orbit.\n\nPluto would take honors of all the planets even though it is closer  than Neptune for part of its orbit.....

If it doesn't move or twinkle, it is the planet Venus.\n\nThis answer brings me to level 3.  Thanks all!

Well, there's nine so far - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.  However, scientists have discovered other planets that orbit our Sun that are even further out than Pluto!  So there's a possibility that we may update our information involving the solar system sometime in the future....

July 29, 2005: "It's definitely bigger than Pluto." So says Dr. Mike Brown of the California Institute of Technology who announced today the discovery of a new planet in the outer solar system.\n\nThe planet, which hasn't been officially named yet, was found by Brown and colleagues using the Samuel Oschin Telescope at Palomar Observatory near San Diego. It is currently about 97 times farther from the sun than Earth, or 97 Astronomical Units (AU). For comparison, Pluto is 40 AU from the sun\nThe planet's temporary name is 2003 UB313. A permanent name has been proposed by the discoverers to the International Astronomical Union, and they are awaiting the decision of this body before announcing the name. \nAm I right U_EVERYONE_K
