If we thought that our tour of the solar system ends at the Neptune or Pluto, we may put ourselves in a very tight space and we have wronged our sun, with its strength 
and did not appreciate what the distances that separate the stars from each other.
and did not appreciate what the distances that separate the stars from each other.
Planets of the solar system very close relative of the sun if we compare it with the space broad interstellar, and as we know that Pluto orbits the Sun at an average distance estimated forty times distance earth from the sun any Forty unit Vklah, though the star closest to our solar system (star thousand Qntrius) away from us 260,000 times the distance between Earth and the sun, between us and the vast desert star and a huge range of wide space between the stars.
More comets, such as Comet Hale Bob Hall Bopp Heikkotik Hyakutake, to Ouhzawa and were relatively close, Hale Bob was a very long way from the sun than any other comet so far, and it was far from the buyer.But those comets, they must have come from somewhere where these comets become very cold (and only steamed quickly due to the effect of the sun) and we can not see them there, they must and they came from a place far away from the sun.In the fifties of the previous century harsh world Jean Oort Jan Oort orbits of comets and conclude that they must and they came from the cloud spherical wide position the sun and can be very large and a diameter of about light-year, and any guilty or body may take millions of years to orbit one cycle around the sun from those distance, has been called the Oort cloud or cloud.But that does not explain the simple note that many of the short-term comets (comets orbits short) does not appear to be Tgi from that distance and in random directions, as they are in those spherical cloud, but it seems the level of consistent and the orbits of the planets of our solar system. Another astronomer, Keiber Kuiper, a proposal at the time showed that these objects came from somewhere much closer to the sun, and settled in the disk level closest explains the orbits of these comets, and fired on the area belt Keiber.
Since then he found dozens of them, and they are objects very faint and very small, and many of them seem colored reddish slightly, which may indicate the possibility of organic compounds (which are essential for life, but does not necessarily mean that these objects by life), and classified Pluto as one of those objects, and these objects probably formed in a different way from other planets in the solar group.
Dwarf planets in Keiber belt
Due to after huge can not see most of the objects in the belt Keiber Kuiper belt enough and good to decide whether they are spherical or otherwise, in the asteroid belt main body only significant and which they apply specifications dwarf planet is Ceres Ceres and of a diameter of about 900 kilometers. Belt objects Keiber Kuiper belt contains a lot of snow inside them, and where the ice is not solid rocks, so those celestial be less resilient to gravity and can easily attract any other offense, and it is easy to take a spherical shape. Best guide to visualize a large body and frosted and takes a spherical shape is the study of the moons of the giant planets. Smaller body and is almost spherical moon Mimas, a moon of the planet Saturn Mimas, which has a diameter of about 400 miles. And several other satellites have diameters about 200 km, not spherical. Between 200 to 400 kilometers an object snowy take spherical shape. Valogram that contain more ice will be spherical at lower volumes which contain the less will be the biggest rocks. And we will take the size of a minimum of 400 kilometers reasonably assume that any offense greater than 400 kilometers in Keiber belt Kuiper belt would be normal spherical shape, and so would be a dwarf planet.
Can not at the present time the number of objects that exceed the diameter 400 km in the belt Keiber, did not exceed the known number to more than a handful of such objects, and even late August 2006 was discovered $ 44 offense pray for this size or larger in the belt of Kuiper, and one is the prophet (Sedna) in the region after the belt. In addition to surveys who by observatories discovered almost about 30 larger body of this size are currently under study.
Dwarf planets and distant example of Pluto Pluto, and Huma Haumea Aires Eris, and Mkmaki Makemake them orbits too far from the sun. It makes them very cold places. And even colder polar land north and south. The internal structures of planets like Earth and Mars made of boulders, the internal structures of the dwarf planets Pluto and other components of the snow, and the snow-covered surfaces too.
It is so cold that the air freezes them. The snow on the roofs of those dwarf planets are not only water ice, but other elements, Pluto's surface contains nitrogen ice and small amounts of methane and carbon monoxide, and possibly ethane. The surface Mkamaki is coated Butlj methane and ethane, and possibly nitrogen. Astronomers have discovered methane ice on the surface of the IRS, either dwarf planet Hoima Haumea is somewhat different, it is covered with water and surface snowfall bright as snow.
On the ground and in normal temperatures we have, nitrogen, methane, carbon monoxide and ethane are all in the gaseous state. On these cold dwarf planets, the gas freezes and turns to ice core.
