The moon would most likely revolve around

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 [ 3 ]. Approximately 4.5 billion years ago, the solar system was a turbulent place — many celestial bodies appear in it, which never became full-flg planets [ 4 ]. Theia was one such protoplanet. of clouds of dust and gas [ 5 ]. Colliding with the Earth, it eject into space part of 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.

It was about the size of Mars and consist

An the Earth as a result of the impact, among other things Paraguay Phone Number List chang the inclination of the axis of rotation. The density of the lunar rock speaks in favor of this theory. The Moon consists mainly of light elements, and its density is, on average, less than that of the Earth [ 6 ]. 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. Another argument “for , along with the fragments of Theia, should have remain near the plane of the Earth’s revolution around the Sun – the ecliptic.

The substance thrown out by the collision

It is in this region that the Moon now rotates. Although this theory was popular at the beginning of the 20th century, subsequent scientific data did not USA CFO confirm it [ 11 ]. For example, calculations show that the spe of the Earth at that time was not so high that a piece of this size could “fall off” from it. Also, if the theory were correct the earth’s equator, but it doesn’t. 3. Simultaneous formation of the Moon and the Earth Another theory of the “Big Three” is the hypothesis of the simultaneous appearance of the Moon and the Earth.
