Rings of Jupiter Rings of Jupiter The planet Jupiter has a system of rings known as the rings of Jupiter or the Jovian ring system. It was the third ring system to be discovered in the Solar System, after those of Saturn and Uranus. It was first observed in 1979 by the "Voyager 1" space probe and thoroughly investigated in the 1990s by the "Galileo" orbiter. It has also been observed by the Hubble Space Telescope and from Earth for several years. Ground-based observations of the rings require the largest available telescopes. The Jovian ring system is faint and consists mainly of dust.
Akaa Solar System Scale Model Akaa Solar System Scale Model Akaa Solar System Scale Model is located at the center of the city of Akaa, Finland. The sun is located at the school campus of Toijalan Yhteiskoulu –school in Toijala district. The scale of the model is 1 : 3 000 000 000, meaning that each centimetre in the scale model represents 30 000 km in real life. The Sun is 464 mm in diameter and the Earth is 4 mm in diameter and located 49.86 meters away from the sun. Neptune is 1500 meters away from the Sun, for example. Akaa Solar System Scale
