1848 – Lassell, William Cranch Bond and George Phillips Bond discover Saturn's moon Hyperion. [142] [143] 1849 – Édouard Roche finds the limiting radius of tidal destruction and tidal creation for a body held together only by its own gravity, called the Roche limit, and uses it to explain why Saturn's rings do not condense into a satellite ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Saturn is known as "Shani" and judges everyone based on the good and bad deeds performed in life. [138] [140] Ancient Chinese and Japanese culture designated the planet Saturn as the "earth star" (土星). This was based on Five Elements which were traditionally used to classify natural elements. [141] [142] [143] In Hebrew, Saturn is called ...
The first human being to reach space (defined as an altitude of over 100 km) and to orbit Earth was Yuri Gagarin, a Soviet cosmonaut who was launched in Vostok 1 on April 12, 1961. The first human to walk on the surface of another Solar System body was Neil Armstrong , who stepped onto the Moon on July 21, 1969 during the Apollo 11 mission ...
Missions to Saturn face competition from missions to other Solar System bodies. The Titan Saturn System Mission (TSSM) was a joint NASA/ESA proposal for an exploration of Saturn and its moons [10] Titan and Enceladus, where many complex phenomena have been revealed by the recent Cassini–Huygens mission.
Moons of Saturn: Originally presented as satellite planets orbiting the planet Saturn. Planetary status later rescinded, leaving them only as satellites. Titan is the second largest satellite in the Solar System, and is slightly larger than Mercury, but less massive. [12] [6] [7] Iapetus: 1671 1700s [13] [11] [6] [7] Rhea: 1672 1700s Tethys ...

Phoebe (/ ˈ f iː b i / FEE-bee) is the most massive irregular satellite of Saturn with a mean diameter of 213 km (132 mi). It was discovered by William Henry Pickering on 18 March 1899 [9] from photographic plates that had been taken by DeLisle Stewart starting on 16 August 1898 at the Boyden Station of the Carmen Alto Observatory near Arequipa, Peru.
