  2. Christiaan Huygens - Wikipedia

    en.wikipedia.org/wiki/Christiaan_Huygens

    He discovered Saturn's biggest moon, Titan, and was the first to explain Saturn's strange appearance as due to "a thin, flat ring, nowhere touching, and inclined to the ecliptic." [10] In 1662, he developed what is now called the Huygenian eyepiece, a telescope with two lenses to diminish the amount of dispersion. [11]

    Mark Robert Showalter (born December 5, 1957) is a senior research scientist at the SETI Institute. [1] He is the discoverer of six moons and three planetary rings. He is the Principal Investigator of NASA's Planetary Data System Rings Node, a co-investigator on the Cassini–Huygens mission to Saturn, and works closely with the New Horizons mission to Pluto.

    The latter include the D Ring, extending inward to Saturn's cloud tops, the G and E Rings and others beyond the main ring system. These diffuse rings are characterised as "dusty" because of the small size of their particles (often about a μm); their chemical composition is, like the main rings, almost entirely water ice. The narrow F Ring ...

  6. Timeline of discovery of Solar System planets and their moons

    en.wikipedia.org/wiki/Timeline_of_discovery_of...

    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 ...

  7. Discovery and exploration of the Solar System - Wikipedia

    en.wikipedia.org/wiki/Discovery_and_exploration...

    Christiaan Huygens followed on from Galileo's discoveries by discovering Saturn's moon Titan and the shape of the rings of Saturn. [14] Giovanni Domenico Cassini later discovered four more moons of Saturn and the Cassini division in Saturn's rings. [15] The Sun photographed through a telescope with special solar filter.

  8. Ring system - Wikipedia

    en.wikipedia.org/wiki/Ring_system

    A ring system is a disc or torus orbiting an astronomical object that is composed of solid material such as dust, meteoroids, planetoids, moonlets, or stellar objects. Ring systems are best known as planetary rings, common components of satellite systems around giant planets such as the rings of Saturn, or circumplanetary disks.

  9. Giovanni Domenico Cassini - Wikipedia

    In addition he discovered the Cassini Division in the rings of Saturn (1675). [7] He shares credit with Robert Hooke for the discovery of the Great Red Spot on Jupiter (ca. 1665). Around 1690, Cassini was the first to observe differential rotation within Jupiter's atmosphere.
