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.
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.
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.
The Andromeda Galaxy is at a distance of about 2.5 million light-years from Earth; or from the Milky Way.
10000 light years
100,000 ly across but only about 1000 ly thick.
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 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 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).
Estimated at about 2.5 million light-years.
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.
The stellar disk of the Milky Way galaxy is approximately 100,000 light years in diameter, and is believed to be, on average, about 1,000 light years thick. It is estimated to contain at least 200 billion stars and possibly up to 400 billion stars, the exact figure depending on the number of very low mass stars, which is highly uncertain. Extending beyond the stellar disk is a much thicker disk of gas. Recent observations indicate that the gaseous disk of the Milky Way has a thickness of around 12,000 light years ---twice the previously accepted value. The Sun (and therefore the Earth and Solar System) may be found close to the inner rim of the Galaxy's Orion Arm, in the Local Fluff inside the Local Bubble, and in the Gould Belt, at a distance of ~25,000 light years from the Galactic Center. So a rough estimate, because there is no real defined outer edge, puts our solar system about 25 thousand light years from the edge of the Milky Way Galaxy.
