Asteroid 2822, Sacajawea, was discovered on March 14, 1980 by Edward Bowell at the Anderson Mesa unit of Lowell Observatory near Flagstaff, Arizona. It has a period of 4 years, 56 days.
Sacajawea was named for a Shoshone Indian woman (whose name is also spelled Sacagawea) who the Lewis and Clark expedition picked up at Fort Mandan near present-day Washburn, North Dakota heading west, along with her white husband, French fur trapper Toussaint Charbonneau. Sacagawea guided Meriwether Lewis, William Clark and their people on the expedition.
Astrologically, Sacajawea seems to indicate helpful, useful, "a native guide".
The glyph for Sacajawea is mine.
