KEPLER 20-F
The Kepler mission:
Kepler is the name of an artificial satellite orbiting the sun looking for extrasolar planets, especially those similar in size to Earth,carrying out what is known as Kepler mission- It was launched by NASA from Cape Canavera, Florida,l on the morning of March 6, 2009. The name of this satellite is due to the astronomer andmathematician Johannes Kepler(1571-1630), discoverer of the three laws that describe the characteristics of the planetary orbits.
The Kepler Mission, is specifically designed to explore a portion ofour region of the Milky Way galaxy to discover dozens of Earth-size planets in or near the habitable zone and determine how many of the billions of stars in our galaxy have such planets.
[pic]The Kepler telescope:
A specific instrument has been specially designed to reach the mission: a 0.95-meter diameter telescope called a photometer or light meter, to obtain theprecision needed to see and measure and Earth-like planet.
How thas it work? The Kepler observatory is in space, staring at one patch of sky all the time which contains 100.00 stars.. If there areplanets orbiting a star, and we see the orbit of that planet edge-on, then once per orbit the planet directly passes between us and the star, blocking its light a little bit. This is called a transit,and the bigger the planet, the more light it blocks.

The Kepler 20 system:
In December 2011, the Kepler telescope has discovered a new planetarysystem, which orbits around a star similar to sun called Kepler 20, in the constellation of Lyra. This star belongs to the same class as our sun, although it is slightly smaller and cooler, and it´s950 light years ago
This system has an unexpected configuration., because it completely differs from our solar system ,where the orbit of small rocky worlds are located near the Sun and the...
