The Magic School Bus Lost in the Solar System their moons (Io for Jupiter, Mimas for Saturn, Miranda for Uranus and Triton for Neptune.) Once on a planet, the user can exit the bus, where a strange satellite called the "whatsit" must be clicked on to bring up an arcade-styled game in which the user, controlling one of the students, must collect one of Ms. Frizzle's tokens (giant coins with Ms. Frizzle's face on them) which provide the user with a clue as to the Friz's whereabouts and activate the "Friz-finder." There are only three clues available, but tokens will still need to be collected to activate the "Friz-finder"
Formation and evolution of the Solar System astronomy, physics, geology, and planetary science. Since the dawn of the space age in the 1950s and the discovery of extrasolar planets in the 1990s, the model has been both challenged and refined to account for new observations. The Solar System has evolved considerably since its initial formation. Many moons have formed from circling discs of gas and dust around their parent planets, while other moons are thought to have formed independently and later been captured by their planets. Still others, such as Earth's Moon, may be the result of giant collisions. Collisions between bodies have occurred continually up to
