What planet is called the dark planet?

Pluto.\n\nPluto\nTiny Pluto is the last planet in our family. The dark, cold planet's average distance from the Sun is a little over 3.5 billion (3,500,000,000) miles. If you tried to step off this distance, you would be over two miles away from your Sun when you reached the location of Pluto. If you got on a jet and flew at 600 miles per hour from the Sun to Pluto, it would take 675 years. If you could drive the same distance, it would take over 5,700 years.

STP rocks. I'm going to have to go with, the dark side of the moon has an earth but you can't really see it and the day after tomorrow is like either Thursday or Fridayish?

"The Dark Side of the Moon".  lol

Saturn.\n\nJust kidding.  It's Jupiter.

UB-313 (also known as "Xena"). This is the only "tenth planet" that has a moon and is larger than Pluto.\n\nThere are several other "planetoids" or "plutinos" including Sedna, Quaoar, Ixion, Varuna, and Orcus.

outer space is not dark.\n\nyou can see something only if it's got some sort of reflective material, or if it emits its own light energy, at the least. so you can't see a cold black planet that doesn't create its own light. but you can see a star that burns stuff to create light. and you can also see stuff such as huge clouds of gas, which reflect light.\n\nand this light, it comes from the zillions of stars that create their own...\n\nso to answer your question in short, outer space *seems* dark because there's nothing that can reflect or produce light, in the direction you're looking.\n\nlook somewhere else, and you can see something shiny and lit.\n\nor, better still, move to a dark-sky location (atleast 30-40mi away from city lights) and see the night sky... you'll be amazed at how light it really is.

My guess would be Pluto

if im understanding your question correctly, it would be the north pole during it's winter, and the south pole during its winter. during their winters, it stays dark almost all day because the earth is tilted. around the 21 of june the sun is directly shining on the tropic of cancer, which means the south pole is really dark. around december 21, it is directly on the tropic of capricorn, so the north pole is dark.

We have 8 'planets' (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune).  We have several more 'dwarf planets.'  \n\nThe difference is that, during planet formation, a planet's gravity will pull in all the material around it, leaving a planet surrounded \nby empty space.  This is referred to as 'clearing the neighborhood.'  A dwarf planet's gravity is not sufficient to pull in all the material around it, so it does not clear its neighborhood.  \n\nPluto is now a dwarf planet, along with several asteroids and other celestial bodies.  In fact, Pluto is a binary planet, because it and it's moon, Charon, orbit each other (the center of Charon's orbit is not a point inside of Pluto, but rather a point between the two bodies).  So Pluto probably won't even be considered a dwarf planet for long.\n\nThis Xena, as you call it, is twice the size of Pluto.  That's what reignited this whole controversy.  It's real name is 2003UB313.  Xena was only given to it as a temporary name.

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

THere is an argument among astromoners as to whether classify the bodies beyond pluto as planets... consider that in the asteroid belt there are many objects orbiting the sun... do we call them all planets?\n\nCurrently there are officially only 9 planets:\nMercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.

Actually, the people who found it honestly want to have it called Xena.\n\nOn July 29, 2005, a Trans-Neptunian object called 2003 UB313 was announced, which on the basis of its magnitude and simple albedo considerations is assumed to be larger than Pluto. This caused its discoverers to call it the "10th planet" of the solar system, although there is no consensus yet on whether to call it a planet, and others consider the new discovery to be the strongest argument yet for demoting Pluto to the status of a minor planet.\n\nBut until then, it's being refered to as Planet X.

Saturn.  It's my favorite planet.  I guess because it is so different from the other planets.

It is in an elliptical orbit past pluto. It is currently called Planet X because it has not been officially recognized as a planet, more study will be required to confirm if it is. Scientists lovingly call it "Xena" after the Warrior Princess show, and they believe it has a moon they call Gabrielle... Astronomers are such nerds.

I'm guessing you mean Sedna.  It is not classified as a planet.\n\nHere's a page on it: http://en.wikipedia.org/wiki/90377_Sedna

Xena.  Planet Xena and her moon Gabriella.  I'm not even kidding, that's what they named it.  There is current debate as to whether or not it is actually planet because it is so small and so far out, but on that note there is also debate still going as to whether pluto is actually a planet or not.  Really, it all depends on how you define planet.  As far as I can tell, the debate is mostly due to how small they are as to whether or not they're actually planets and not just planetoids.
