Welcome to our Solar / Planetary Walk which has been established in memorial to Alfred Piff, a longtime member of MBG and supporter of education for all. As you travel along the walk, you will experience the scale model of our solar neighborhood. Our walk is approximately .79 miles, and each planet is marked by Planetary Art Posts created by Nancy Thomas. Scanning the QR at each post will give access to information about each planet. Enjoy your walk!
With over 300 times the mass of Earth, Jupiter is the largest planet and is named for the king of the Roman gods. It has no actual surface, just increasingly dense layers of gas and liquid hydrogen, helium, methane, and ammonia compounds. Its Great Red Spot is a hurricane-like storm three times the diame-ter of Earth. Jupiter spins very fast (just under 10 hours) so looks striped and generates a huge magnetic field. It also has the most moons, including Io (which has many volcanoes), Europa (it has the possibility of life in its ice-covered ocean), and Ganymede (the largest moon in the entire solar system). Gravity at Jupiter’s cloudtops is 2.53 g’s.
