This is part of a whole solar-system model that spans north Georgia.
Mars is “the red planet”, and a good candidate for the next planet Humans might live on. It’s the fourth planet from the Sun, after Earth and before the asteroid belt, Ceres and then Jupiter. Mars’ diameter is 6771km⁘. Its average orbit distance from the Sun is 228,000,000km, or 1.52AU, or 13 light-min⁘ .
The model of Mars is 11.1cm in diameter⁘, and is about 3.743km distant⁘ from the Georgia Capitol dome in Downtown Atlanta.
Mars has two moons. Phobos is 22km in diameter⁘, which makes it 0.36mm in the model⁘, orbiting Mars at about 9380km away⁘, or 15.4cm away in the model⁘. Demios is 12km in diameter⁘, which makes it 0.2mm in the model⁘, about the size of a mote of dust. Its orbital distance from Mars is 23,460km⁘ or about 38.5cm from the model Mars⁘.
