Mr. Kay's Science 8

Our galaxy, the Milky Way, is about 100,000 light years in diameter. It is estimated to include roughly  10 billion stars, one of which is our sun. A supermassive black hole is believed to reside at the center of the galaxy where the concentration of stars is the greatest. The galaxy rotates very slowly making  one full revolution every 225 million years. The closest star to us, besides our sun, is Proxima Centauri . It is 4.2 light years away or approximately 25 trillion miles. A light year is the distance traveled in one year at the speed of light. (about 300,000,000 meters per second for a year)
