Saturn is named after the Roman god of wealth and agriculture, who was the father of the god Jupiter.Its astronomical symbol has been traced back to the Greek Oxyrhynchus Papyri, where it can be seen to be a Greek kappa-rho ligature with a horizontal stroke, as an abbreviation for Κρονος (), the Greek name for the planet ().

Titan orbits Saturn at 20 Saturn radii or 1,200,000 km above Saturn's apparent surface. From Titan's surface, Saturn, disregarding its rings, subtends an arc of 5.09 degrees, and if it were visible through the moon's thick atmosphere, it would appear 11.4 times larger in the sky, in diameter, than the Moon from Earth, which subtends 0.48° of arc.
Radio Garden is a non-profit Dutch radio and digital research project developed from 2013 to 2016 by the Netherlands Institute for Sound and Vision (under the supervision of Martin Luther University of Halle-Wittenberg's Golo Föllmer), by the Transnational Radio Knowledge Platform and five other European universities.
Sketch of a circumlunar free return trajectory (not to scale), plotted on the rotating reference frame rotating with the moon. (Moon's motion only shown for clarity) In orbital mechanics, a free-return trajectory is a trajectory of a spacecraft traveling away from a primary body (for example, the Earth) where gravity due to a secondary body (for example, the Moon) causes the spacecraft to ...
Saturn's orbit plane is inclined 2.485 degrees relative to Earth's, and Jupiter's is inclined 1.303 degrees. The ascending nodes of both planets are similar (100.6 degrees for Jupiter and 113.7 degrees for Saturn), meaning if Saturn is above or below Earth's orbital plane Jupiter usually is too. Because these nodes align so well it would be ...

It is also designated Saturn XV. Atlas is the closest satellite to the sharp outer edge of the A ring , and was long thought to be a shepherd satellite for this ring. However, now it is known that the outer edge of the ring is instead maintained by a 7:6 orbital resonance with the larger but more distant moons Janus and Epimetheus . [ 7 ]
Voyager 1 is now using a radio transmitter it hasn’t relied on since 1981 to stay in contact with its team on Earth while engineers work to understand what went wrong. ... The system of radio ...
