The Sun, with a surface temperature of over 5,000 degrees, is located outside the entrance to the Charles Hayden Planetarium at the Museum of Science.
Mercury is missing! The scale model of the first (and smallest) planet in the solar system (part of the Museum's Community Solar System) was formerly located in the lobby of the museum.
Venus, the hottest planet in the solar system, is located inside the stairwell on the roof level of the Museum of Science parking garage.
Unfortunately, the Earth is nowhere to be found. Its scale model (from the Museum of Science Community Solar System) was removed in 2009 during the Hotel's exterior renovations.
Mars, which boasts the largest volcano in the Solar System (Olympus Mons, 3 times higher than Mount Everest), is located on the second floor of the Cambridgeside Galleria Mall by the south escalators.
Jupiter, the largest planet in the solar system (and the neighborhood gravitational bully!), is located next to Rosie's Bakery in the main train terminal.
Saturn, which is light enough to float in a big enough bathtub, is represented in the Museum of Science Community Solar System with a model in the DeVito Music Room. If you find it, create a check-in!
Uranus, tilted sideways and orbiting the Sun like a rolling barrel, is represented in the Museum of Science Community Solar System by a scale model near the entryway. If you see it, create a check-in!
The model of Neptune (the first planet to be predicted before it was observed) from the Museum of Science Community Solar System is no longer displayed in the Food Court.
Pluto, formerly the last planet and currently a dwarf planet, is represented in the Museum of Science Community Solar System by a scale model on the station platform. If you see it, create a check-in!
