Discovery and exploration of the Solar System Domenico Cassini later discovered four more moons of Saturn and the Cassini division in Saturn's rings. Edmond Halley realised in 1705 that repeated sightings of a comet were recording the same object, returning regularly once every 75–76 years. This was the first evidence that anything other than the planets orbited the Sun. Around this time (1704), the term "Solar System" first appeared in English. In 1781, William Herschel was looking for binary stars in the constellation of Taurus when he observed what he thought was a new comet. Its orbit revealed that it was a new planet, Uranus, the first
WorldWide Telescope spacecraft and orbital reference frames can be added and visualized in the Solar System Mode using the layer manager. Users can query the Minor Planet Center for the orbits of minor bodies in the solar system, such as Sandbox The Sandbox mode allows users to view arbitrary 3d models (OBJ or 3DS formats) in an empty universe. For instance, this is useful to explore 3D objects such as molecular data. WorldWide Telescope was designed as a professional research environment and as such it facilitates viewing of user data. Virtually all of the data types and visualizations in WorldWide Telescope can
