Seven Earth-sized planets discovered orbiting a neighbour star

-
This discovery has raised hopes of finding alien life beyond our solar system much sooner than previously expected, with a new generation of telescopes expected for the next decade.
It is the very first time that so many Earth-sized planets (seven) have been found orbiting around the same star. A  part from the size, other conditions, such as distance to the sun or the fact that we are dealing with rocky planets, resemble our own  home.

Eris, Makemake and Haumea / Eris, Makemake y Haumea

Eris, Makemake and Haumea are dwarf planets located behind Pluto, in areas of the solar system known as scattered disk and Kuiper Belt. They are known as dwarf planets likewise Ceres and Pluto, but unlike these two have not been seen in sufficient detail to show that completely fit the definition of planets. Eris has a mass larger than Pluto and Makemake and Haumea are still under investigation. Besides these three bodies fall into a new category called "plutinos" or "trans-" by many. Although the IAU does not specify a specific name, are often referred to by the abbreviation TNO (Trans neptunian object). This category of objects similar to Pluto only applies to dwarf planets if they are trans-Neptunian objects and their periods, inclinations and eccentricity are similar to those of Pluto and therefore are on the scattered Disk, the Kuiper Belt or the Oort Cloud. In addition, there are a few bodies who are candidates for recognition as "dwarf planets"

Uranus / Urano

Uranus is the seventh planet from the Sun and the third largest. The main feature of Uranus is the inclination of its axis almost ninety degrees with respect to its orbit, an inclination which is not only limited to the same planet, but its rings, satellites and magnetic field. Uranus has the most uniform surface of all the planets by their characteristic blue-green color produced by the combination of gases in its atmosphere. Although at first glance it may not seem, it has a system of rings, including one blue. It is also a gaseous planet. As happens with Venus, Uranus has a retrograde motion, turning clockwise. The planet has an atmosphere formed by a mixture of hydrogen and helium and traces of methane (being about 15% of its planetary mass) and the mantle would be formed by ice and chemical oceans, water, ammonia and methane, providing a high electrical conductivity. Uranus has 27 known moons, Titania and Oberon being the largest with a similar size (1580 and 1520 km in diameter
