In space formed planet similar to our Earth?


In space, found a system with two suns (HD 113766), in which, it seems, there are active processes of planet formation, very similar to our Earth. This solar system is located at a distance of 424 light years, and the age of the Sun (about 10-16 billion years) are just right for the formation of planets.

This solar system found thanks to NASA’s space telescope Spitzer.

Scientists have discovered an enormous ring of warm dust that is sufficient for the formation of planets the size of Mars or even more. This ring is rotated around distant star, which is only slightly heavier than our Sun. This ring of dust (from which, as scientists think, planets form) is in the middle of a "liveable" section, in which water can exist in liquid form. Earth, for example, is just in the middle of such a "habitable" area.

Age of the Sun (10 billion years) is also ideally suited for the formation of planets. If the system was too young, the protoplanetary disk would be full of gas, and this would lead to the formation of gas giant planets (Jupiter-like). If this solar system would be too old, the "clumping" of cosmic dust and the formation of rocky planets would have already happened. Thus, it appears that the conditions of formation of Earth-like planets are not only to be in the right place at the right time, next to the sun. Need just the right "mix" space "building materials."

Spitzer telescope helped determine that cosmic dust in the HD 113866 system is in a transition stage between the stage of formation of icy comets and asteroids stone formation stage. That is, Cosmic dust is located in a state where just beginning to form planets.

So, we can say that we are witnessing stage of planet formation, which may become as viable as our Earth. Meanwhile, we can only say that the observed planet grows and grows bigger every day and is ready to surprise and confound astronomers around the world.
