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.
The solar system appears to have a new ninth planet. Today, two scientists announced evidence that a body nearly the size of Neptuneâbut as yet unseenâorbits the sun every 15,000 years. During the solar systemâs infancy 4.5 billion years ago, they say, the giant planet was knocked out of the planet-forming region near the sun. Slowed down by gas, the planet settled into a distant elliptical orbit, where it still lurks today.
