Bow shocks in astrophysics magnetized, such as Jupiter or Saturn. Earth's bow shock is about thick and located about from the planet. Bow shocks form at comets as a result of the interaction between the solar wind and the cometary ionosphere. Far away from the Sun, a comet is an icy boulder without an atmosphere. As it approaches the Sun, the heat of the sunlight causes gas to be released from the cometary nucleus, creating an atmosphere called a coma. The coma is partially ionized by the sunlight, and when the solar wind passes through this ion coma, the bow shock appears. The first
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
