Bok is a lunarcrater that is located on the far side of the Moon. To the southeast is the Sniadecki crater; to the north is McKellar crater, and further to the west is De Vries crater.
The rim of Bok is well-defined and is not significantly eroded. The inner walls slope gently down to the nearly level interior floor, which has a central peak near the mid-point. There is a slight inward bulge along the northwest wall.

By convention these features are identified on Lunar maps by placing the letter on the side of the crater mid-point that is closest to Bok crater.
In 1975 Bok coauthored the statement Objections to Astrology (The Humanist, 1975)[1], which was endorsed by 186 professional astronomers, astrophysicists, and other scientists, including nineteen winners of the Nobel Prize.
Bart Bok was an exceedingly popular personality in the field of astronomy, noted for his affability and humor, as well as his capacity for drinks.
Bokcrater on Mars is named for a geographical location in Papua New Guinea and not for him.
