Satellite Craters
Surrounding Aristarchus are several smaller craters, many of which are probably secondary craters. Secondary craters form when large blocks ejected from the primary crater reimpact the surface at high velocities. By convention these features are identified on lunar maps by placing a letter on the side of the crater midpoint that is closest to the primary crater.

Famous quotes containing the words satellite and/or craters:
“Books are the best things, well used; abused, among the worst. What is the right use? What is the one end, which all means go to effect? They are for nothing but to inspire. I had better never see a book, than to be warped by its attraction clean out of my own orbit, and made a satellite instead of a system.”
—Ralph Waldo Emerson (1803–1882)
“Listen.
We must all stop dying in the little ways,
in the craters of hate,
in the potholes of indifference....”
—Anne Sexton (1928–1974)
