About Kepler Crater
 Kepler (lunar crater) - Wikipedia
It is a southern lunar rayed impact crater between Oceanus Procellarium and Mare Insularium, lying just west-southwest
of Copernicus Crater.  The central crater is 22 miles in diameter while the bright rays extend out about 180 miles.
 It is named for Johannes Kepler, a 17th century German astronomer and mathematician.

About Copernicus Crater
 Copernicus (lunar crater) - Wikipedia
 Located at 10-degrees North, 20-degrees West near the southern rim of Mare Imbrium, Copernicus is a relatively young, well-preserved rayed lunar crater measuring 92 km (58 miles) in diameter.  Peaked mountains rise from the center to a height of 800 meters (2,600 feet).  It was named after Polish astronomer Nicolaus Copernicus (1473-1543).

  Copernicus & Eratosthernes Craters and southern Mare Imbrium
 


Photo of a portion of the northwest moon taken from my backyard in Los Angeles, CA in the early morning
of October 17, 2022.  The large bright crater at the lower left is Copernicus.  Just left of center is
Eratosthenes Crater (see video on Eratosthenes).  Mare Imbrium is the smooth lava plane at the upper right.  The mountains to its
south are thought to have formed 3.9 billion years ago when a proto planet hit the moon.  Basaltic lava later filled it in.
