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.
100,000 ly across but only about 1000 ly thick.
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.
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.
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 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.
It would take approximately 100,000 years to travel from one end of the Milky Way to the other at the speed of light, which is about 186,282 miles per second. However, with current technology, it would take much longer to traverse the Milky Way.
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.
