10 Most Unique Planet

The universe is so vast. Human inhabited planet, planet earth is one of a thousand, a million, or even one of the trillions of planets scattered in outer space. Based on these facts, of course you never or often assume there may be other than life on earth. Scientists believe the possibility is there and from time to time continue to seek clues to discover a new world.
In 1990, scientists discovered a glimmer of hope by finding the number of planets outside our solar system (exoplanets). The planets are very diverse. Starting from the planet of fire, giant planets, rocky planets, planets that have no stars, and much more. Until now, the discovery of exoplanets planets reach 230. Here is a list of ten exoplanets

1. The Fire Horse
Quote from 

Planet 51 Pegasi b is the first exoplanet discovered planet hunters in 1990. Jupiter-like planet, but the heat temperature is given the nickname Bellerphon, mythical Greek hero who tamed the winged horse Pegasus. Giving nicknames are based on the constellation Pegasus, the location of the planet.
2. Nearest Neighbor Earth
Located only 10.5 light-years, Epsilon Eridani b is closest to the Earth exoplanets. The planet orbits its star so far away from water or life there impossible.

3. Planets Without Stars
There are a number of exoplanets that have a star or the sun is more than one, even to have three sun. As with the Planemos. The planet is just a "float" around the star away without anything.

4. The Agile
The planet sweeps-10 is only 740,000 miles from its star. I was so close, the planet called ultra-short-period planets (USPPs) it only takes less than one day to orbit. One year there equal to ten hours on earth.

5. World Fire and Ice
The planet is "locked" on the star, like a moon has always been a satellite of the earth. So, one side of the planet Upsilon Andromeda b is always facing there. This position creates the highest temperature so far known to astronomers. One side of the planet is very hot like lava, while the other side very cold temperature.
6. Giant ring
Planet orbiting the star Tau 4 is Coku exoplanets youngest aged less than one million years. Astronomers detect the presence of the planet from a large hole of the planet's rings. The hole size ten times larger than Earth.
7. The Old Pacific
Planet of the oldest, also called this primeval world was about 12.7 billion years. The scientists suspect the planet was formed eight billion years before Earth materialized and only two billion years of disputing the Big Bang event. This discovery raises the discourse that life may occur earlier than expected so far.
8. Shrinking Planet
Similar to the sweeps-10, HD209458b planet orbiting very close to its star that the planet's atmosphere swept away by stellar winds. Some scientists estimate the planet's loss of ten thousand tons of material every second. In the end, perhaps only the core of the planet will be left.
9. The Thick Atmosphere
Planet HD 189733b is the first planet atmosphere "smell" by scientists. By analyzing the light from the planet's star system, astronomers say the planet's atmosphere thick fog covered by some sort of similar to a grain of sand. Unfortunately, the water was not detected in the planet. However, planet hunters suspect there is life behind the thick fog.
10. Earth's twin?

Exoplanet Gliese 581 C is currently much interest to scientists around the world. Because the smallest planet outside solar system is located in the "safe zone". That is, the planet is located not too far nor too close to its star, the same as the position of our earth to the sun.This discovery raises the probability there is water or even life there. The planet is 50 percent larger and five times more massive than Earth.Could there be other life out there? The scientists say could further reveal that in 2013, when construction of high-tech telescopes called the James Webb Space Telescope (JWST).
