Walk From The Sun To Neptune In 2,880 Feet

If you're ever in  the St. Louis area and have an interest in astronomy, you might want to visit the Delmar Loop Planet Walk in University City-a scale model of the solar system. 

There are nine stations-one for each planet plus the Sun. (Pluto is not included, because it's not considered a planet any more.)  Each sign has a depiction of the planet at the top and then a list of fun facts about it below.

If you're familiar with the area, the Walk is on the north side of the 6100 to 6600 blocks of Delmar. It starts near the Moonrise Hotel and goes west. Each inch of the sidewalk represents 80,000 miles, and the marker's distance from one to the next is to scale.

  1. Very interesting. AND, believe it or not, I thought about doing this somewhere in the St. Louis area but even more to scale than just distance. I would have a model of each plant. The problem comes in with Mercury. To be able to see a realistic model of Mercury, everything else gets a lot bigger. I've got all the specs written down somewhere around here. And if I remember correctly, Pluto (still a plant when I did this) was 10 to 12 miles away from the Sun.

  2. I will have to take my oldest great grandson to see this. he would be very interested. Thanks for the tip!

    1. You're welcome. And of course he would also be interested in stopping by the candy store or some place that would give him a scoop of ice cream.
