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.

How many AU's is the Milky Way galaxy 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.
How far away is the edge of your Solar System?
our solar system is on a spiral on one of the milky ways many spirals. we are in the milky way galaxy which is 100 000 light years in diameter and 10 000 light years thick at the centre.
How many galaxies like our own would it take if they were placed edge to edge to reach the nearest galaxy?
Less than one. * The Milky Way (our galaxy) has a diameter of about 100,000 light-years. * According to the Wikipedia, the Canis Major galaxy is at a distance of 25,000 light-years from our Solar System. However, its status as a galaxy is disputed (in other words, it may not be a galaxy). * On the other hand, the Sagittarius Dwarf Spheroidal Galaxy is at a distance of about 70,000 light-years from the Solar System - still less than the diameter of our galaxy. Note that the distances given are from our Solar System; NOT from the center of our Milky Way.
How many years would it take a spacecraft traveling at the speed of light to cross the milky way galaxy?
The very fastest human-made spacecraft ever aren't out of this solar system yet, and they were launched in the 70s."Billions of years" is, if anything, an understatement.
Are there nebulas in the milky way?
A supernova is a star which has effectively exploded. There have been many in our galaxy which we call the Milky Way. There have also been supernovas in other galaxies too.
How many light years from the milky galaxy and the Andromeda galaxy?
The Milky Way galaxy and the Andromeda galaxy are approximately 2.5 million light-years apart. This makes Andromeda the closest spiral galaxy to our own Milky Way. Both galaxies are part of the Local Group of galaxies.
How many light years the galaxy to galaxy?
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).
How many light years away is the farthest star from us in the milky way galaxy?
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.
How many light years is the Milky Way across?
100,000 ly across but only about 1000 ly thick.
What distance is the milky way galaxy from the sun?
The sun is one of the many stars in the milky way - our galaxy. Sol, our Suns name is about 25 light years from the center of the Milky Way.
How many AU's is the Milky Way galaxy 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.
How many light years across is your galaxy?
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 milky way galaxy can be characterized as kind measurement in light-years how many stars?
The question is somewhat confusing, so I am not sure what you mean. The Milky Way is a galaxy; it has a diameter of about 100,000 light-years; it has between 100 and 400 billion stars (the exact number is not known).
The milky way is approximately how many light years away?
Technically, zero.We are in it.The sun is one of the 200 - 400 billion stars in the Milky Way galaxy.
How many years is it from earth to the galaxy?
The Earth is in the Milky Way galaxy, so the answer is "Zero."
How many miles is the sun from the center of the milky way?
Our sun (also known as Sol) is about 80,000 light years from the center of the Milky Way galaxy. A light year is about seven trillion miles, so 80,000 light years is about 560 quadrillion miles.
How far away is the edge of your Solar System?
our solar system is on a spiral on one of the milky ways many spirals. we are in the milky way galaxy which is 100 000 light years in diameter and 10 000 light years thick at the centre.
