Interactive 3D model of Solar System Planets and Night Sky

Description 3D simulation of the Solar System and night sky in real time - the Sun, planets, dwarf planets, comets, stars and constellations. - Heliocentric view with real-time positions of planets and planetary orbits - Schematic and realistic sizes of the planets and distances between them - Movement of the planets in time to see how they move in relation to each other - Virtual Orrery - Planetary exploration with info texts and additional views such as structure - Dwarf planets (Pluto, Ceres, Haumea, Makemake. Eris) and their orbits - Comets (Siding Spring, Lovejoy 2013, Lovejoy 2011, Panstarrs, ISON, Halley) - positions and trajectories - Stars and constellation of the night sky as viewed from a given location - Changes in the night sky during night, month and year - Searching of the stars and constellation, ecliptic line, grid lines and more
