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.
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
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 ...
If observed from the vantage point of space, the rings would still be all accounted for. A view of Saturn's rings from NASA's Hubble Space Telescope captured on June 20, 2019.
Even if you don’t have a decent telescope or a powerful pair of binoculars, you’ll still have a chance to see Saturn in the night sky this week.

Uranus, when discovered in 1781, was the first planet discovered using technology (a telescope) rather than being spotted by the naked eye. Theoretically, in a typical dark sky, the dark adapted human eye would see the about 5,600 stars brighter than +6 m [6] while in perfect dark sky conditions about 45,000 stars brighter than +8 m might be ...
