The first theory is the co-formation theory. The co-formation theory also know as the condensation theory, says that the moon was formed at the same time as the earth. The theory states that the solar system was formed out of the solar nebula. The co formation theory explains why the moon appears to be in the location it is in. The weakness of this theory is because if the moon and the earth were condensed together the gravitational force of earth would have caused the moon to become part of the planet and not a natural satellite. We should not accept this theory because there is no real good evidence to support this.
The second theory is the capture theory. The capture theory states a rocky body formed somewhere in the solar …show more content…
The fission theory proposes that the moon was once apart of the earth and somehow separated from the earth early in the history of the solar system. This use to be the most acceptable theory, they thought it was thought possible since the moons composition resembles part of the earths mantle. The fission theory gives a good explanation for the similar siderophiles, but it also explains the moons iron core. However, the moon lacks "fossil evidence" of a fast spin, and doesn't orbit the earth following the equatorial plane. In order for the fission theory to be true, the earth would have had to be spinning so fast , which is now believed to be highly impossible. We should not accept this theory because there is a lack of evidence that the earth could have been spinning that
