To provide defense against these sporadic attacks, the early settlers erected a series of forts in the area. Wood's Fort guarded the Forks-of-the-River just downstream from Newport, and McCoy's Fort and Whitson's Fort defended the area to the south.
The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the Sun, with most of the remaining mass contained in Jupiter.
This causes Vega to produce 35-40 times the energy of the sun, which in turn shortens its lifetime. At about 500 million years, Vega is already middle-aged. Currently it is only about a tenth the age of our sun, and will run out of fuel in another half-billion years. In astronomer-speak, Vega is an âA0V main sequence star.â
