I think it's difficult for many people to really grasp how tiny we are relative to the universe. I've gathered up some good size comparative photos to demonstrate our significance in a relatively spatial manner.

The first image shows the earth relative to the Moon. The Moon is on average 384,403km away or approximately 1.255 light seconds away.

Earth's Mean radius: 6,371.0 km
Moon's Mean radius: 1,737.10 km

Next is a photo comparing the size of Earth to the size of the Sun. The Sun is approximately 93million miles from Earth and it takes light an average of 8.33 minutes to travel this distance.

Sun's Equatorial radius 6.955×10^8 m

Our Solar System alone spans billions of kilometers.

And here is our Sun again, just as a spec to the side of the Galactic Equator.

Again, a spec amidst our home the Milky Way Galaxy.

The Milky Way in all its glory, with the Sun hidden away.

The approximate diameter of the Milky Way is 100,000 light years. And here is our galaxy, merely a spec among other galaxies within our "local group" of galaxies. Our local group alone is about ten million light years across.

Next, our "local group" in relation to other nearby groups of galaxies. 1 Mpc = 3,261,636.26 light years. This is still just a tiny section of our universe!

Our local group is a part of the Virgo Supercluster!

Last one... can you find your way home? There are more than one hundred billion (10^11) galaxies in the Universe, each containing hundreds of billions of stars!

i have one to continue your second post.this compairs the Sun's size to Sirius, Pollux,and Arcturus.

this one is the mind-boggler.the Sun,in this pic,is only one pixel in size.

For various reasons - our relative small size being the most obvious - we do not feel the effects of the speed at which we travel. Perhaps you understand that we are in constant motion relative to our cosmic surroundings, but here are a few in depth details:

The speed of Earth's rotation along its axis is approximately 1,000 miles per hour.

The speed of Earth rotating around the Sun is approximately 67,000 miles per hour.

The Sun (along with us!) circles the Milky Way at a speed of about 486,000 miles per hour.

The Milky Way and the Andromeda galaxy are approaching each other with a speed of about 300,000 miles per hour.

This does not contain accurate representations of relative distance. I just wanted to show direction of speed.
