Venus May Once Have Suffered A "Moon-Forming" Impact, But The Resulting Satellite Wouldn't Have Stuck Around For Long
It seems a large companion is difficult for a planet that size and distance from the Sun to hold on to, which might be bad news for life on Venus-like exoplanets.
Giant impact could have formed an intact moon within five hours, simulations suggest
New Southwest Research Institute (SwRI) modeling, conducted in collaboration with scientists at the University of Arizona, shows fundamental differences in how the moon may have formed from the giant impact that created the Earth–moon system. The new results used state-of-the-art computational techniques that factor in the material strength of the two colliding planets. These impact simulations could change how researchers understand moon format…
In the collision of the young Earth with Theia, a factor that has been mostly neglected so far may have decided whether the moon was created directly or only grew from a debris ring. New simulations take into account the temperature-dependent strength of the two bodies. Under certain cooler conditions, a largely intact lunar body forms in it already after about five hours.

New simulations of the SwRI and the University of Arizona show that the Moon formed intact in five hours after the giant impact. The entry SwRI and Arizona Simulations reveal the formation of the Moon in just five hours after the impact aparece primero en Merca2.
