The Solar System: The Sun
The Sun is the star at the center of our solar system and by far the largest object in the solar system
The Planets: Saturn
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. Cassini–Huygens is an unmanned spacecraft sent to study the planet Saturn. The probe arrived at Saturn in 2004.
The Planets: Pluto
Pluto, once considered the ninth and most distant planet from the sun, is now the largest known dwarf planet in the solar system. In 2006, Pluto was reclassified as a dwarf planet, a change widely thought of as a demotion.
The Planets: Mars
Mars is the fourth planet from the Sun. Presently, information is being relayed from nine active probes on or in-orbit around Mars, including six orbiters and two rovers. Recently, Europe's ExoMars mission landed on Mars on October 19th 2016.
