The Earth, Moon, and Mars, to scale, with 3D surface terrain and full color from the latest NASA space imaging.
To extend this set to include all of the inner planets, the matching-scale Venus and Mercury are available here: https://www.shapeways.com/model/3013707/
[See also the solar system set
(but note that set is a logrithmic scale, not linear like this one)]
Earth: 50mm (2 inches) diameter
Mars: 27mm (1 inches) diameter
Moon: 13mm (0.54 inches) diameter
Scale: 1 : 251102362
The Earth and Mars globes are hollow, with a 12mm (1/2 inch) hole at the south pole, giving them a flat bottom on which to sit without rolling, but each also comes with a matching cap/plug to seal that hole, to form a full sphere. (The moon is solid)
The parts are shipped to you directly from the 3D-printer, and so the package unfortunately does not include labels or instructions.
Special thanks to NASA / JPL-Caltech, for allowing the use of their planet surface terrain and mapping.
