How Many Solar Systems Are In Our Galaxy?:

“For many years scientists have studied our own solar system. But until the last few years, we knew of no other solar systems. This may seem surprising, as the Sun is one of about 200 billion stars (or perhaps more) just in the Milky Way galaxy alone."

Corot Overview:

“COROT is the first mission capable of detecting rocky planets, several times larger than Earth, around nearby stars (planets outside our Solar System are referred to as ‘exoplanets’)."

In All The Universe, Just 15 Percent Of Solar Systems Are Like Ours:

“In their quest to find solar systems analogous to ours, astronomers have determined how common our solar system is. They've concluded that about 15 percent of stars in the galaxy host systems of planets like our own, with several gas giant planets in the outer part of the solar system."

How Was the Solar System Formed?:

“Scientists aren't completely sure how the solar system formed, but most agree the best explanation is that a cloud of molecules collapsed inward on itself, forming our solar system about 4.6 billion years ago."

Solar System Guide:

“The Universe is a very big place, and we occupy a very small corner of it. Known as the Solar System, our stomping grounds are not only a tiny fraction of the Universe as we know it, but is also a very small part of our galactic neighborhood (aka. the Milky Way Galaxy)."

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)."

The Origin of Our Solar System - How the Sun and the Planets Formed:
http://www.enchantedlearning.com/subj...

“Our solar system formed about 5 billion years ago, from an enormous cloud of dust and gas, a nebula.The Sun, like other stars, was formed in a nebula, an interstellar cloud of dust and gas (mostly hydrogen)."
