New theory on the Moon's formation: It may have formed within five hours
A new study reveals that following the giant impact 4.5 billion years ago, the Moon could have formed within hours.
According to a scientific study published in The Astrophysical Journal Letters, the Moon may have emerged within hours as a result of a Mars-sized body colliding with Earth 4.5 billion years ago.
New approach to the collision theory
In the latest study, the structural strength of the material in the two colliding celestial bodies was taken into account for the first time, causing theories to change.
The role of rock physics and temperature
Scientists previously assumed that the intensity of the impact melted and vaporized the rocks. New simulations showed that temperature-dependent geological strength directly affects the outcome.
The Moon formed within five hours
In scenarios where Earth and a proto-planet named Theia were colder, it was determined that a solid Moon could emerge just five hours after the collision.
Questions that maintain their mystery
Although the research sheds light on the formation timeline, the striking similarity in the composition of Earth and the Moon is not yet fully explained.
