The Little Planet Factory 3D-prints true-to-scale solar systems, heavenly bodies and planets, such as the 109-millimeter-diameter Sun and the associated Jupiter (10 millimeters) and the Earth at 1 millimeter with a scale of 1:12 trillion. If you wanted to place these things to scale, the earth would have to be 11 meters away from the sun and Jupiter 60.
