It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.

— Neil Armstrong

If you could see the earth illuminated when you were in a place as dark as night, it would look to you more splendid than the moon.

— Galileo Galilei,Dialogue Concerning the Two Chief World Systems, 1632.

It is tiny out's inconsequential. It's ironic that we had come to study the Moon and it was really discovering the Earth.

—Bill Anders, Apollo 8, quoted in the 2008 Discovery TV seriesWhen We Left Earth.

(The Moon) was a sobering sight, but it didn't have the impact on me, at least, as the view of the Earth did.

—Frank Borman, Apollo 8, Interview for the PBS TV showNova, 1999
