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.
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.
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.
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.
yes.............
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.
The Andromeda Galaxy is at a distance of about 2.5 million light-years from Earth; or from the Milky Way.
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).
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.
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.
100,000 ly across but only about 1000 ly thick.

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 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).
Technically, zero.We are in it.The sun is one of the 200 - 400 billion stars in the Milky Way galaxy.
The Earth is in the Milky Way galaxy, so the answer is "Zero."
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.
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.
