The Milky Way is the galaxy that contains the Solar System. It is a prohibited control galaxy 100,000-120,000 many decades across containing 200–600 billion dollars celebrities. The galaxy is approximated to contain 50 billion dollars planet's, 500 thousand of which could be located in the human friendly location of their parent or guardian star. The spinning rate: 1 per 15 to 50 thousand decades. The galaxy is also moving at a amount of 552 to 630 km per second with regards to the family member shape of reference. It’s approximated age is 13.2 billion dollars decades of age, nearly as old as the Universe. The Milky Way is part of the Local Group of galaxy.

How many species on Earth?
To suppose that earth is the only populated world in infinite space is as absurd as to believe that in an entire field sown with millet, only one grain will grow. –Metrodorus of Chios, 4th century B.C.
Our sun is one of a 100 billion stars in our galaxy. Our galaxy is one of billions of galaxies populating the universe. It would be the height of presumption to think that we are the only living thing in that enormous immensity -– Wernher Von Braun
Estimated the number of species at nearly 8.8 million: 6.5 million on land, 2.2 million in ocean
So far, only 1.9 million species have been found.
26 times more animal than plant species; The research estimates that animals rule with 7.8 million species, followed by fungi with 611,000 and plants with just shy of 300,000 species.
