The prompt was man in the Moon, but I have always seen a rabbit, so that's what I drew!!! 8-P

Running my little world mapping page (more a schematic), I get this example-

42981.92 km in circumference, 588.06 m. km^2 in area, with five seas and one continent larger than all of the Earth’s landmass. The five seas are actually one ocean surrounding this and are still larger than all of the Earth’s oceans because the world surface area is so large. 

Area# 1 61.65 m. km^2 sea, Area# 2 78.51 m. km^2 sea, Area# 3 195.42 m. km^2 land (>all the Earth’s landmass and Eurasia!), Area# 4 86.74 m. km^2 sea, Area# 5 77.2 m. km^2 sea, Area# 6 88.54 m. km^2 sea, remainder: 0 m. km^2 33.23% land 66.76% sea

The next random world is smaller- 30806.2 km in circumference, 302.08 m. km^2 in area. This one is mostly land, the reverse of a water world like Earth or the first large world above. The largest sea is about the size of the Indian Ocean and the largest landmass is larger than Africa and Eurasia. The two remaining oceans are larger than Earth’s smallest, the Arctic Ocean, and are a little larger and a little smaller than the southern ocean around Antarctica. They’re about the same area as North and South America, and in fact the two smaller land masses are about the same size as  North America and together are a little smaller than the second largest, which is comparable to Eurasia.

Area# 1 25.19 m. km^2 sea (>Southern Ocean/North America)

Area# 2 23.6 m. km^2 land (<North America)

Area# 3 19.03 m. km^2 sea (>Arctic Ocean/South America)

Area# 4 66.86 m. km^2 sea (<Indian Ocean)

Area# 5 89.35 m. km^2 land (>Afro-Eurasia)

Area# 6 25.66 m. km^2 land (>North America)

Area# 7 52.36 m. km^2 land (>Eurasia)

remainder: 0 m. km^2 63.22% land 36.77% sea
