A new supercomputer simulation has shown that the moon would have been formed through a collision of earth and a planet called Theia around 4.5 billion years ago. As per the simulation, the Theia planet might have been the size of Mars. Scientists from the UK have created many animations of simulations. Each simulation has shown a different amount of spins, the wandering plant Theia might have taken to approach the earth. Experts have seen that each simulation shows different explosive patterns of rocky debris stemming from the point of impact. They believe that it would have clustered together to form the moon. These simulations are based on the widely known ‘Big Splash’ theory or ‘Giant Impact Hypothesis’. As per the astronomers, Theia would have been around 3792 miles in diameter, which might have crashed into the early earth, which has a diameter of 7917 miles. It would have resulted in a ring of debris around the home planet, later it would have come together to form the moon. Experts have said this event might have occurred around 4.5 years ago and nearly 153 million years after the formation of the solar system.
This simulation explains how relatively large the moon is as compared to other rocky bodies in space. The author of the study, Sergio Ruiz Bonilla has said that adding different amounts of spins to Theia in simulations and having no spin at all results in a whole unusual range of effects for what might have occurred when the early earth would have hit the massive planet billions of years ago. Experts have said that some of the simulations have been able to form an orbiting clump of objects, which are not much smaller than the moon. These simulations have shown a disc of extra material well as surrounding the post-impact earth, which might help the clump to develop in mass over time. Experts from Durham University have created their supercomputer recreation on the DiRAC high-performance Computing facility in association with the University of Glasgow. They have identified the rocky materials that would have blown from the source of the collision. These rocky materials might have been created to form the moon, as per the experts.
The simulated crash with the earth has formed different outcomes, which depends on the size and direction of Theia’s early spin, from no spin at all to spinning like a pool ball anti-clockwise and clockwise both. During an extreme spin in a clockwise direction, the collision has combined the two objects. While, during an extreme spin in an anti-clockwise direction, experts have noticed a hit and run impact. However, where no spin has been added to Theia, experts have seen a self-gravitating clump of material with a mass of 80 percent of the moon. When experts have added a small amount of spin to the simulation, another moon-like object has been formed. The resulting clump of materials, which has settled into an orbit near the post-impact earth, might have grown bigger by sweeping the disc of debris surrounding the earth. Experts have said that the simulated clump of material contains a small iron core similar to the moon. Experts have received a number of outcomes, which depend upon the introduction of the spins to the Theia plant before its collision into the early earth. They have said that outcomes of no spin and a small amount of spin deserve to be called a proto moon.
