Larger craters can have terraces, central peaks, and multiple rings. Copernicus is a large crater (93 kilometers or 60 miles wide) on the Moon. The inner walls of the crater have collapsed to form a series of step-like terraces, and a central peak is visible in the center of the image. Apollo 17 image courtesy of NASA.

Self-published authors could be paid as little as $0.006 per page read under new rules planned by Amazon. Writers who make their works available through Amazonâs Kindle Owners Lending Library, and a similar service called Kindle Unlimited, will no longer be paid per copy downloaded following a move announced last week.
The KDP Select Global Fund â the amount that is split between KDP Select authors at the end of each month â varies from month to month, but is at $2 million for July 2014. For Kindle Unlimited, the author receives a payout anytime someone downloads their book and reads past 10%.
