Answer:
The Sun formed, probably along with other stars, within a large molecular cloud
A close binary consists of two stars that orbit each other every few days
A brown dwarf is a "star" so small in mass that its core never gets hot enough to sustain nuclear fusion reactions.
Most of the gas remaining from the process of star formation is swept into interstellar space by a protostellar wind
As a protostar's internal temperature increases, its growing thermal pressure helps slow its contraction due to gravity.
