Assuming that the Sun’s orbit about the center of the galaxy is circular, we know that the circumference of that circular orbit is 2*pi*r, where r is the distance from our Sun to the galactic center. Since distance = rate * time, we know that time = (2*pi*r)/rate = (2*pi*2.5×10^(17) km)/220 km/sec =~ 225 million years. Jeff Mangum Find GIFs with the latest and newest hashtags!

Figuring out how much energy permeates the center of the Milky Way — a discovery reported in the July 3 edition of the journal Science Advances — could yield new clues to the fundamental source of our galaxy’s power, said L. Matthew Haffner of Embry-Riddle Aeronautical University. But, the Sun is also revolving around our Milky Way galaxy, and it takes it 225 to 250 million years to complete one revolution. The Milky Way is a barred spiral galaxy having a diameter of around The mass of people hides the edges of the room. It’s exactly the same from our position in the galaxy. The Milky Way as seen in different wavelengths of light. The most familiar view is optical The Milky Way is approximately 890 billion to 1.54 trillion times the mass of the Sun in total (8.9 × 10 11 to 1.54 × 10 12 solar masses), [ 22][ 23][ 111] although stars and planets make up only a small part of this. Estimates of the mass of the Milky Way vary, depending upon the method and data used. .
