What are the dimensions of the model of the solar system built in Maine? The Science Museum in Maine (USA) is not rich enough to have a real planetarium. So his collaborators built a 1:93 scale model of the solar system. It stretches along the local highway for 000 miles (000 kilometers). The idea arose when the director of the museum noticed that the length of the road numerically corresponds to the distance from the Sun to Pluto, expressed in astronomical units (40 astronomical units). In this model, the Sun in the form of a 15-meter ball is located in the museum building. Planets made of steel and fiberglass are placed along the road. Jupiter has a diameter of 1,5 meters, Pluto - about 2,5 centimeters. Near Pluto is its satellite Charon with a diameter of 9 millimeters. If you run or ride a bicycle on the side of the road at a speed of 11 kilometers per hour, this will correspond to movement through the solar system at the speed of light. On this scale, the radius of the Oort sphere would be about 200 thousand kilometers, and the distance to the nearest star (Proxima Centauri) would be 425 thousand kilometers (for comparison: the average distance of the center of the Moon from the center of the Earth is 384 kilometers).

In Geneva, for 2 centuries, there has been a tradition to declare the onset of spring by a special decree when the first leaf is blooming on the "official chestnut tree" growing under the windows of the cantonal government building. According to statistics, most often spring was announced in March, although often earlier, and in 2002 the chestnut tree completely blossomed on December 29th. The most paradoxical year was 2006: first spring was announced in March, and then again in October, as the tree unexpectedly bloomed again.
