Answer 2

"Encounter hypothesis:

The encounter hypothesis of the planet is related to solar family formation. This is one of the "earliest theorie". A five billion years ago, it suggested that a rogue star or intergalactic star or star which is without gravitational pull which passed "close to the Sun".

At the same time, some material was stripped with tidal force with the Sun and the intergalactic star in the form of "hot gas". This theory also says that all the planets are formed by these ejected materials from the Sun."
