100,000 ly across but only about 1000 ly thick.
The Milky Way galaxy is 100,000 light years across.
The Milky Way is estimated to be about 2,000 light years thick, but about 100,000 light years long/far... Which i guess you can tell, thats a lot.
The nearest galaxy to our Milky Way is the Andromeda galaxy, which is about 2.5 million light years away (that is not including the Large and Small Magellanic Clouds, small, irregular "satellite" galaxies of our own).
It is estimated that the Milky Way is about 100,000 light years wide. In other words, it takes light about 100,000 earth years to travel from one edge right across to the far edge.
If the milky way galaxy is 100,000 light years across and if the universe is 13 billion years old, you would have 130,000 milky way galaxies, end on end to the edge of the universe.
The Milky Way galaxy is approximately 100,000 light-years (30 kiloparsecs, 9x1017 km) in diameter, and is considered to be, on average, about 1,000 ly (0.3 kpc) thick .
The Andromeda Galaxy is at a distance of about 2.5 million light-years from Earth; or from the Milky Way.
10000 light years
Same as Earth. The distance from Earth to Mars is insignificant in comparison to the distance scales in the Milky Way. - About 20,000 light-years.
The Milky Way galaxy, in which we live, is about 50,000 light years in radius, and we're about 40,000 light years out from the center. So the farthest away stars are probably about 90,000 light years away.
Yes it is. All the stars that we can see are in the Milky Way galaxy. Stars in other galaxies are too far away from us to be able to see them properly. That is even true of many stars in the Milky Way Galaxy.
Estimated at about 2.5 million light-years.
Light-years is a distance, not a time measurement. If you are asking how many light-years a person would have to travel to be outside of the Milky Way galaxy, the answer depends on the "direction" one wishes to use when exiting. The Milky Way, relatively speaking, is almost flat, with a thickness of only 9.26 quadrillion kilometers which is roughly 1000 light-years. While this sounds like a large distance, compare that to the width which is between 9,260 to 11,353 quadrillion kilometers or 100,000 to 120,000 light-years across. Therefore, if you went the thin way, it would be a maximum distance of 4.63 quadrillion kilometers or 500 light-years. If you went the thick way, the distance would be sufficiently larger.
