- Lake Michigan (/ˈmɪʃɪɡən/) is one of the five Great Lakes of North America. It is the second-largest of the Great Lakes by volume (1,180 cu mi (4,900 km3)) and the third-largest by surface area (22,404 sq mi (58,030 km2)), after Lake Superior and Lake Huron. To the east, its basin is conjoined with that of Lake Huron through the 3+1⁄2-mile (5.6-kilometre) wide, 295-foot (90-metre; 49-fathom) deep Straits of Mackinac, giving it the same surface elevation as its easterly counterpart; the two are technically a single lake.

ALPHARD (Alpha Hydrae). Not all that well known among bright stars, but surprisingly prominent, Alphard both dominates and lies at the heart of the relatively dim constellation Hydra, the Water Serpent (the longest constellation of the sky), hence clearly deserves to be Bayer’s Alpha star.
