Of the nine bodies currently recognized as planets, \nPluto is the farthest from the Sun (and thus\npresumably the coldest).  We don't know the exact\nsurface temperatures, but some estimates are:\n\n1) -228 to -238 C   (see reference #1)\n2) -205C (see reference #2)\n3) -233° to -223° C (see reference #3)

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.

Scientists using NASA's Spitzer Space Telescope have discovered and directly imaged a small brown dwarf star, 50 times the mass of Jupiter, orbiting with a planet around a Sun-like star. Such an arrangement has never before been seen but might be common, the scientists say, leading to solar systems with distorted planetary orbits.\n\nKevin Luhman of Penn State University is the lead author on a report describing this discovery, which will be published in The Astrophysical Journal. The discovery concerns a class of the coldest brown dwarfs, called T dwarfs.\n\n\nThe detailed research paper on T dwarf - Ref\nhttp://www.science.psu.edu/alert/Luhman9-2006-2.htm

Not at all. You are correct the plance you are talking about is called the ecliptic plane.  almost all the planets fall on the ecliptic plane (to within a few degrees anyway, all but pluto but it's not a planet anymore) . You would still have to dodge asteroids, comets and other things by going 90 degrees to the ecliptic but they are fairly rare.

Antartica because it is at the bottom of the globe and it is mostly snowy there

the weather is pretty cold because it it far from the sun.It's temperature is -214 C.Its atmosphere is mainly made of hydrogen and methane gas.It has seasons different from us because it is tipped over its side

Equator!\n\nThe Arctic Circle is in the North.  The Tropic of Capricorn is in the South.  So the Equator is between them.

I'll assume you meant "in the solar system"\n\n -  "pluto" isn't a planet! It's just a big block of dirty ice...\n\n -  The biggest planet is Jupiter, and is made of gas.\n\n -  The smallest would be mercury, which is right next to the sun.\n\n -  It would be hard to say which planet is "medem", since there are really big planets (the gas giants: Jupiter, Saturn, Uranus, and Neptune), and really small ones: (the inner planets: Mercury, Venus, the Earth and Moon, and Mars)

Hi. On the surface it has quite a range. Venus is about 700 degrees, Neptune is cold. At the cores though there are all hot. I would guess about 1500-2000 F degrees on average.

Surprisingly, there is no total agreement about the size of our Solar System. Some say it's defined by the orbit of the outermost planet (used to be Pluto), while others say it's where the Sun's heliosphere ends. Then there's the definition that I personally favor -- the Oort Cloud of comets.\n\nHere's a breakdown of the three major sizes favored:\nPluto orbit - 5,900^6 km\nHeliosphere - 2.2^10 km \nOort Cloud  - 1.5^13 km (1.6 light years)

The perihelion is a planet or comet's closest approach to the Sun. The Earth is at perihelion (the Earth is closest to the Sun) in January.

Because Mercury's rotation is almost perpendicular to its orbital plain, the north pole always sees the sun just above the horizon. The insides of craters would never be exposed to the Sun and scientists suspect that they would remain colder than -161 C. These freezing temperatures could trap water outgassed from the planet, or ices brought to the planet from cometary impacts. These ice deposits might be covered with a layer of dust and would still show bright radar returns.
