Astronomers have discovered a planetary system like our own!

Is there somewhere in the universe, a planet similar to Earth's twin? Scientists have no doubt that the space is full of heavenly bodies, to which you can apply the term "second Earth". There are also systems planet that looks like a mirror image our Solar System. Researchers have discovered a celestial band, whose arrangement is deceptively close to our system. Yet none of the previously discovered by astronomers systems was not so very similar to the solar system, like the recently discovered by researchers at the Massachusetts Institute of Technology. Experts, using data from the Kepler Space Telescope, studied carefully Kepler 30th star system The work examined the relationship in which they are celestial bodies and the central star of this system. The results were astounding. It turned out that the prevailing arrangement in this system is very similar to the order which prevails in the solar system. Experts have determined that all three planets that are part of that system , are from four to twelve times larger than Earth. According to the researchers, the system Kepler-30 may have originated in the same way as the solar system, ie with a relatively flattenedlayermaterial near the star. experts have no doubt that the latest discovery will bring a breakthrough in research on egzoplanets.

Giant impact hypothesis

Giant impact hypothesis

Great deal hypothesis is a hypothesis that explains how the moon formed. This hypothesis states that the cooling of the solar system, during heavy bombardment, Earth had no moon. But there was a Mars-size planet orbiting the earth that the earth was one of the Lagrangian points. After a few million years, the planet today Tya say it was out of the stable situation and hit the ground. As a result, it was part of the earth as a molten ball and then passing out and freezing, the moon formed today.
One hypothesis, the table share the same orbit as the earth and you know, around 60 degrees from Earth Lagrange point of the position that has arisen. [2] about the raw mass of the planet Mars to the table will grow as baby more stable Lagrange points was unable to be present. As a result, the angular distance of the Earth and Tay Ah began to change as fluctuating, Tay knew then ended the conflict on Earth has become increasingly accessible. This conflict is about events 4,533,000,000 years ago, seems to have occurred. Oblique angle to the table to know the district budithyeoteumyeo, teyiah body pieces were characterized Tay Ah, most of the mantle and the Earth's mantle is a significant amount was ejected into space. Tay Ah center of the Earth's core sank into the nucleus. According to computer simulations are ejected into space forming a ring around the earth, mass of materials teyiah 2% level, respectively, half of them together over a period of 100 years of the current is said to form the Moon. Pre-crash earth's rotation and the ecliptic inclination somewhat angst is not considered, the conflict in the aftermath of the Earth's rotation period is five times faster and the Earth's equator, the moon's orbit, and nearly matched so the slope was changed. Astronomers Apollo collected in Moon mission, similar to that of the Earth showing oxygen isotope giant rocks is seen as indirect evidence of a collision. Months of the composition of the anorthosite crust and rich in minerals such as creep and the fact that a significant amount through the month, once melted, enormous energy from the collision of the magma ocean would have been enough to make. Evidence of iron nuclei through several months if there is less that its size can be inferred. In particular, the mean density, moment of inertia, the characteristics of rotating, magnetic core size of the moon through the reaction caused the entire diameter can be seen that only 25 percent (the other terrestrial bodies of rock the size of the full diameter of the nucleus of a 50% reaches), according to the theoretical collision conditions of the material from Earth's mantle and the moon sprang Tay Tay Ah ah sank into the core of the Earth's core can be explained that, the Earth-Moon angular momentum of a planetary system constraints are satisfied.

Theia the planet which created our moon

Theia the planet which created our moon. Theia is the unofficial name of a hypothetical protoplanet, which is, according to the collision theory of lunar formation collided about 4.5 billion years ago with the proto-Earth. Theia itself was destroyed in the collision, the impact the resulting fragments have been collected in an orbit around the Earth. In the course has been formed from the moon. According to this theory, Theia was about as big as Mars, and has one of the models for the Trojans as the Earth-Sun Lagrange point L4 system formed before it collided with Earth. From a comparison of the isotopes in the Earth and moon rocks could be derived that derives the bulk of the material from which the moon was formed, the mantle of the proto-Earth. The material apparently Theias caused no change in the isotopic composition of the proto-Earth. This fact points to the origin of the protoplanets: Theia was apparently at the same distance from the Sun as the proto-Earth. Due to the large sun near the protoplanet sat largely composed of silicates.
The theory, according to the Lagrange point L4 Theia in the Earth-Sun system is created, speaks to this possibility. Recent simulations that involve the chaotic effects of motion in the vicinity of Lagrange, show that a body that is formed in L4, can actually achieve the necessary speed to create the moon.
