A recent study has pointed that the moon may have been formed after a huge Mars-sized body hit a magma-layered infant Earth.
Readings from the past had suggested that the Earth may have been formed about 4.5 billion years in the past, and the moon must be a little younger than the prior. For three decades, the standard explanation for the origin of the moon was that the moon must have been formed because of the clash between two new born planets or early universes. One of which was considered as the infant Earth and the other must have been a Mars-sized body, popularly dubbed as Theia. It was named after the mother of the moon from Greek Mythology. The moon then converged to become the sphere it has remained till date.
The Massive Impact Hypothesis appeared to clarify numerous insights concerning Earth with the moon; for instance, the huge area of moon in relation to the Earth’s rotation and revolution rates of both the bodies. In any case, the last 15 or so years had been relevant for these theories as many alternatives had been suggested to surpass the cons of this theory.
Latest Computer-generated display of the massive impact theory frequently stated that about 60 % of the moon should be composed of materials from Theia. And the new model recommends that the content of debris generated by an impact from molten earth would have been equivalent to the present mass of the moon. However, earlier works in this theory had proposed that in order to create the lunar body, the impact would initially produce the amount of leftover equivalent to four times the moon’s current mass. Researchers in future should estimate higher weight for Theia and count in the revolution of the old Earth to check whether that may prompt enough left over to shape a body that is comparable with the size of the current moon.
