Discover three planets similar to the Earth.

For the first time, researchers discovered three planets potentially livable, worlds similar to Earth orbiting a dwarf star 40 light years in another stellar system.

The dwarf star, known as TRAPPIST-1, is not the type of star that scientists hope it will be a center on which revolve planets. Is at the end of the area of criteria which is considered as star: has half the temperature and a tenth of the mass of our sun. TRAPPIST-1 is red, a little bigger than Jupiter and is very tenuous to be seen or even with amateur telescopes on Earth.

But these stars dwarf, together with the called brown dwarfs, have a life extensive, are common in the Milky Way and represent 25-50% of the stellar objects in the galaxy.

These stars had not been detailed until the researcher Michaël Gillon of the University of Liege in Belgium decided to take the risk to study the space around these celestial bodies.

Less is known of the third planet, which receives double the radiation from the Earth, but also potentially is in the livable zone.

The two planets nearest to the star always face from one side to the star, so that one side of the planet is always of night and the other day.
