The 10th Planet outside solar system!

The universe is unique and so broad, the existence of life on earth other than a big question mark and maybe for some people there is no answer. The scientists believe the possibility exists, and from time to time continue to look for clues to discover a new world.

In 1990, scientists discovered a glimmer of hope by finding a planet outside our solar system (Exoplanet). The planets are very diverse. Starting from the planet of fire, giant planets, rocky planets, planets that have no stars, and more. Until now, the discovery of 230 planets Exoplanet. Here is a list of ten Exoplanet 2009 version of

1. The Fire Horse

Planet 51 Pegasi b is Exoplanet hunters first discovered the planet in 1990. Jupiter-like planets, but the hot temperature was given the nickname Bellerphon, the hero of Greek myth who tamed the winged horse Pegasus. Giving nicknames are based on the constellation Pegasus, the location of that planet.

2. Earth's Nearest Neighbor

Is only 10.5 light-years, Epsilon Eridani b is Exoplanet closest to the earth. The planet orbits its star so far away from the water or life there impossible.

3. Planets Without Stars

There are a number of Exoplanet that have a star or the sun is more than one, even down to having three of the sun. As with the Planemos. The planet is just "floating" around a star just like that without anything.

4. The Swift

The planet sweeps-10 is only 740 000 miles from its star. I was so close, a 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 of Fire and Ice

This planet is "locked" in the star, like a moon has always been a satellite of the earth. So, one side of the planet Upsilon Andromeda b was 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. Ring Giants

Planet orbiting the star Tau 4 Coku Exoplanet youngest is aged less than one million years. Astronomers detect presence of planets was a big hole from the planet's rings. Holes have size ten times larger than Earth.

7. Si Tua Bangka

The oldest planet also called primeval world this was about 12.7 billion years old. The scientists suspected that such planets are formed eight billion years ago before the earth materialized and only two billion years at odds of occurrence of the Big Bang. This finding raises the discourse that life may happen earlier than expected so far.

8. a Shrinking Planet

Similar sweeps-10, the planet HD209458b orbits very close to its star that the planet's atmosphere is swept away by stellar winds. Some scientists estimate the planet is losing ten thousand tons of material every second. In the end, perhaps only the core of the planet that will remain.

9. The Thick Atmosphere

Planet HD 189733b is the first planetary atmospheres "smelled" by scientists. By analyzing light from the planet's star system, astronomers say the planet's atmosphere is thick fog covered by some sort of similar to grains of sand. Unfortunately, the water was not detected on the planet. However, planet hunters suspected there was life behind the thick fog.

10. twins on Earth?

Gliese 581 C is Exoplanet currently attracting considerable attention of scientists around the world. Section, the smallest planet outside solar system are located in the "safe zone". That is, the planet is located not too far or too close to its star, the same as our earth with the sun's position. These findings raise the probability that there is water or even lives there. This planet is 50 percent larger and five times more massive than Earth.

Could there be other life out there? Scientists say it could further reveals that in 2013, when construction of high-tech telescope called the James Webb Space Telescope (JWST) completed.
