At the boundary of our solar system can “hide” two planets – TVNZ

The famous Spanish astronomer, Professor Complutense University of Madrid, Carlos de la Fuente Marcos, said that the number of planets in our solar system may be more than eight or nine if you count Pluto in respect of which the views of the astronomical world divided. These planets may be on the edge of the solar system in the Kuiper Belt, which consists of many small celestial bodies that remained after its formation. Previously it was thought that the largest inhabitant of this belt is Pluto now recognized small planet. Now, however, there are indications that there may be a minimum of two much larger object.

This is the conclusion astronomers on the ground that the bodies in the Kuiper belt moving at the most strange and unpredictable trajectories. This can be explained by the fact that they attract some invisible to us large celestial bodies.

The theory of Professor Marcos explains Independent, based on the Kozai mechanism, according to which, to put it simply, large bodies affect the orbits of small and distant objects. By the size of the planet invisible to exceed the Earth. Talking about their existence only recently, after the discovery of 100 astronomical units from the star HL Tauri disk of gas and dust from which planets can form.

We find two new planets very similar to Earth

The telescope Kepler discovered eight new planets, two of which are very similar to Earth and is therefore extremely interested astronomers. They are in the habitable zone and named Kepler-438b and Kepler-442b. Planet similar to Earth in size. They are more of our planet by 12 and 30%, respectively, and revolve around their stars – red dwarfs at the right distance to there could be water. Their somewhat cooler stars of our sun. Kepler-438b is at a distance of 470 light years from Earth, and Kepler-442b – 1100 (Details)
