Astronomers studies the Milky Way more in depth
Astronomers study the orbital motions and its outer stars in an attempt to find the mass of the Milky Way. The estimated mass is about 600,000,000,000 to 3 trillion times the mass of the sun. Based on research in 2005, the Milky Way is about 13.6 billion years old. "Milky Way." The Gale Encyclopedia of Science. Ed. K. Lee Lerner and Brenda Wilmoth Lerner. 4th ed. Detroit: Gale,
