Einstein and Einstein A Craters of the moon

Some of the craters on the moon are thought to be as old as 2 billion years. Pictured here is a false-color image of two craters on the western side of the moon, both named for Albert Einstein (1879-1955). Einstein A lies squarely in the middle of the Einstein Crater, making it the younger of the two impacts. “Einstein A reveals most of its original structure, including a raised rim and ejecta blanket, and is therefore a relatively young crater as compared to Einstein, whose original structure has been somewhat degraded over time by smaller impacts,” NASA says.
