Although the state of alaska has more square mileage than any other u. s. state, it is one of the least populated in the country. which is the most probable reason for this

A great question for me to answer I use to live there

Alaska gets extremely cold. and there are alot of dangerous parts that are hard to get to. alot of places in Alaska have to roads you would have to get flown into these parts. also in the summer it stays light 24/7 and in the winter it's always dark, this gets people really depressed.

Ifound this on google “solar system formation. scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). this explosion made waves in space which squeezed the cloud of gas and dust.” i hope this you for what your looking for.
