Daniel Hoyt, an early settler and surveyor, proposed the city name. Hoyt, who later was elected the first township clerk, suggested the name because it was a Greek word meaning order and harmony.
Cosmos was incorporated as a village on Sept. 21, 1926. The cosmic theme is carried on in the city streets named for planets and constellations, and the rocket decorating the water tower.
The city covers a one-mile-square section of land. The 1990 population was 610 in the city, and an additional 269 people living in the surrounding Cosmos Township.
The Luce Line trail will be built through the city park on the south side of Highway 7, then cross to the north side of Hwy. 7, east of the intersection of Hwy. 7 and Milky Way Lane.
The average daily traffic count at the intersection with Hwy. 7 is 2,450 to 2,950 vehicles (1991 figures). The trail will then follow along the Hwy. 7 right-of-way until it rejoins the railroad right-of-way.
