Size Of Milky Way In Light Years. Jan 20 2015 NASA estimates the galaxy at 100000 light-years across. The Galactic Plane Above - An all-sky plot of the 25000 brightest whitest stars B-V0 shows how these stars are concentrated along the Milky Way. This brings the Milky Ways size up to that of Andromeda. Ben Tennyson and.
When we look in the plane of the disk we see the combined light of its stars as the Milky Way. Our galaxy probably contains 100 to 400 billion stars and is about 100000 light-years across. Instead of extending nearly 100000 light-years from one side to the other it would be more like 160000 light-years wide. Apr 04 2013 Think the Milky Way is big. Since one light year is about 95 x 10 12 km so the diameter of the Milky Way galaxy is about 95 x 10 17 km in diameter. Its thickness is 1000 light years throughout most of the disk but there is a.
Jan 26 2009 The Milky Way is a huge disk roughly 100000 to 120000 light years across.
The stellar disk of the Milky Way Galaxy is about 200000 light-years 910 17 km in diameter and is considered to be on average about 1000 light years thick. Since one light year is about 95 x 10 12 km so the diameter of the Milky Way galaxy is about 95 x 10 17 km in diameter. Then in 2015 researchers showed that a distance of 150000 light-years was closer to the mark. And the findings indicate that the Milky Way stretches roughly 200000 light-years across. The Milky Way is only 100000 light years in diameter. Apr 04 2013 Think the Milky Way is big.
