How Does The Solar System Compare To Our Galaxy?
Well, from the preceding you can easily see that the Solar System is minuscule compared to the Milky Way.
To put it in numbers:
• The Solar System is .0032% the size of the Milky Way.
• Traveling at the speed of light you could cross the solar system from edge to edge (3.2 ly) in 3.2 years.
• It would take 100,000 years to cross the Milky Way at the speed of light.
Just to gain another reference point, our nearest spiral galaxy, the Andromeda galaxy (M31) is 2.4 to 2.9 million light years from us, and it is about 250,000 ly in diameter. Very big! But, consider the size of the known Universe—156 billion ly wide!
So, size is relative, you can almost always find something that is bigger or smaller. The Solar System is large but relative to our galaxy it is very small. Looking on a smaller scale, we humans are challenged just to travel a few hundred miles to get into orbit, and even more so to get to our own natural satellite.
Will we ever conquer these vast distances and travel to the stars? I think we will, in long time—but that, too, is relative.
