I've recently been pondering the following thought experiment:
Assume that the Earth was to gain a large amount of mass in a very short time, which effectively increase the mass of the Earth by approx. 1.5 * 1021 kg, and this in course of say five years.
What I've been trying to figure out is what effect this would have on the Earths orbit around the Sun and, more interestingly, the Moons orbit around the Earth. Would this sudden increase result in an eventual collision between the Moon and Earth, given Earths increased gravity?
