At different times astrophysicists put forward various theories. Until the s, three of them were the most common – they even got the name “Big Three”. But after the American lunar expitions of the s and s, the one that did not enter the top three became generally recogniz: today, most scientists believe that the Moon was form as a result of a collision of our planet with another celestial body. Below we explain it, talk about the hypotheses of the “Big Three” and share some more bold assumptions about the origin of the moon.
The Moon was form due to the fact
Collision of the Earth with another planet According to Dominican Republic Phone Number List the theory of a giant collision or otherwise impact theory (from the English impact – impact), that some celestial object crash into the young Earth. scientists Hartmann and Davis (William K. Hartmann, Dr. Donald R. Davis) in . A little later, a hypothetical object that collid with the Earth was nam Theia (Theia) – in honor of the mother of the moon goddess Selene from Greek mythology . Approximately . billion years ago, the solar system was a turbulent place — many celestial bodies appear in it, which never became full-flg planets . Theia was one such protoplanet. It was about the size of Mars and consist of clouds of dust and gas.
The density of the lunar rock speaks
Colliding with the Earth it eject into space part of USA CFO the substance of the earth’s mantle. Gravity complet the process: the eject debris began to rotate in near-Earth orbit and gradually gather into the moon. And the earth as a result of the impact, among other things, chang the inclination of the axis of rotation. in favor of this theory. The Moon consists mainly of light elements, and its density is, on average, less than that of the Earth . This does not contradict the impact theory: the Moon was partially form from the substance of the earth’s mantle, and not from the heavier and denser earth’s core.
