Well, if the sun is the Moonrise Hotel, and "5 billion" is Cicero's Restaurant, Uranus would be parked right at Brandt's Cafe.
That's the gist of the new Delmar Loop Planet Walk opening on November 8 with a "Big Bang" party and ribbon-cutting. The interactive walk - a la the Loop's already-popular St. Louis Walk of Fame - represents a scale model of the solar system.
Instead of stars molded into concrete, the Planet Walk is comprised of five-foot-tall signs bearing fun facts of astronomy.
At 2,800 feet long, the walk will begin at the Moonrise with a model of the sun and follows west, ending at Cicero's, with Neptune's likeness.
And what about Pluto, you ask? "Pluto has been demoted," explains Stephen Walker, the Planet Walk's creator. "The International Astronomical Union met in 2006 and decided Pluto would be downgraded to a dwarf planet."
The hotel's developer, Joe Edwards, adopted the idea immediately and proceeded to drum up $20,000 in funding from University City and St. Louis.
"Throughout the world there's about 24 such walks like this," says Walker. "Twelve of them are in the U.S, but apart from one in Wisconsin, we're pretty much loners here in the Midwest -- so it makes it that much more exciting."
