It's not often that we feature a non-astronomical object as PotW, but one nice "spin-off" from the plethora of solar eclipse images which sent in was this nice shot of the famous Barringer meteor crater in Arizona.  It was taken by Andrew as he left Pheonix using his iPhone 6s on a Delta Airways flight.

The crater is about 1 mile wide and 570 ft deep and was formed about 50,000 years ago when a meteorite travelling at about 20 km/s impacted the Arizona desert. The explosion was equal to 2.5 megatons of TNT.  The meteorite was made of nickel-iron and is estimated to have been about 45 meters (150 ft) across, weighing about 270,000 metric tons (300,000 tons).
