The Otford Solar System is a scale model of the solar system constructed in and around the village of Otford in southeast England.
The model, formed of reflective domes on plinths with information plaques, accurately represents the positions of the planets at the turn of the millennium, 1st January 2000, all in relation to the Sun. The Sun and the nearby planets are all located in the village playing field with short walks to the next nearest planets.
Interestingly, the model not only extends to the distant planets Neptune, Uranus and Pluto (a couple of miles outside of the village!), it also includes four of the nearest stars, to scale and at approximately at the correct distance. Due to the vast distances involved the nearest star to the Sun, Proxima Centauri, is located in Los Angeles, Barnard’s Star in Port Stanley, Falkland Islands, Sirius in Sydney, Australia and Ross 154 in Christchurch, New Zealand!
