The dense main rings extend from 7,000 km (4,300 mi) to 80,000 km (50,000 mi) away from Saturn's equator, whose radius is 60,300 km (37,500 mi) (see Major subdivisions). With an estimated local thickness of as little as 10 meters (32' 10") [ 40 ] and as much as 1 km (1093 yards), [ 41 ] they are composed of 99.9% pure water ice with a ...
Saturn’s rings are seen as viewed by NASA’s Cassini spacecraft, which obtained the images that comprise this mosaic at a distance of approximately 450,000 miles from Saturn April 25, 2007.
The phase curve of Saturn, according to Schmude [21] demonstrating the opposition effect of the ring system. The brightness of the Saturn system depends on the orientation of its ring system. The rings contribute more to the overall brightness of the system when they are more inclined to the direction of illumination from the Sun and to the ...
In the case of a planet or asteroid, the absolute magnitude H rather means the apparent magnitude it would have if it were 1 astronomical unit (150,000,000 km) from both the observer and the Sun, and fully illuminated at maximum opposition (a configuration that is only theoretically achievable, with the observer situated on the surface of the Sun).
On Monday, Aug. 2, Saturn will officially reach opposition, meaning that it will appear opposite of the sun from the perspective of the Earth. Saturn is at opposi See the rings of Saturn during ...
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.
A truly dark sky has a surface brightness of 2 × 10 −4 cd m −2 or 21.8 mag arcsec −2. [9] [clarification needed] The peak surface brightness of the central region of the Orion Nebula is about 17 Mag/arcsec 2 (about 14 milli nits) and the outer bluish glow has a peak surface brightness of 21.3 Mag/arcsec 2 (about 0.27 millinits).

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.
