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 the most distant of the five planets easily visible to the naked eye from Earth, the other four being Mercury, Venus, Mars, and Jupiter. (Uranus, and occasionally 4 Vesta, are visible to the naked eye in dark skies.) Saturn appears to the naked eye in the night sky as a bright, yellowish point of light.
The first successful probe to fly by another Solar System body was Luna 1, which sped past the Moon in 1959. Originally meant to impact with the Moon, it instead missed its target and became the first artificial object to orbit the Sun. Mariner 2 was the first planetary flyby , passing Venus in 1962.
Keeler was the first to observe the gap in Saturn's rings now known as the Encke Gap, using the 36-inch refractor at Lick Observatory on 7 January 1888. After this feature had been named for Johann Encke, who had observed a much broader variation in the brightness of the A Ring, [3] Keeler's contributions were brought to light. [4]
NASA’s James Webb Space Telescope has captured its first near-infrared observation of Saturn, highlighting details in the planet’s atmosphere and rings. Saturn’s rings shine in new Webb ...
The final images to trickle onto NASA's servers will show the spot on Saturn's dark side toward which Cassini will dive — "Cassini's final home inside the planet Saturn itself," Spilker said.
Pioneer 11 image of Saturn.. Saturn was first visited by Pioneer 11 in September 1979. It flew within 20,000 kilometres (12,000 mi) of the top of the planet's cloud layer. Low-resolution images were acquired of the planet and a few of its moons; the resolution of the images was not good enough to discern surface featu
