Four planets — Venus, Saturn, Jupiter, and Mars — are bright enough to see with the naked eye this month. Uranus and Neptune are visible with a telescope. Uranus and Neptune are visible with a ...
An alignment of six planets will dazzle in January 2025. Venus, Mars, Jupiter, Saturn, Uranus and Neptune will align in the night sky. "The whole month of January is a great time to see the ...
The moons Io, Ganymede, Europa, and Titan are visible. A great conjunction is a conjunction of the planets Jupiter and Saturn, when the two planets appear closest together in the sky. Great conjunctions occur approximately every 20 years when Jupiter "overtakes" Saturn in its orbit.

Titan orbits Saturn at 20 Saturn radii or 1,200,000 km above Saturn's apparent surface. From Titan's surface, Saturn 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.
The sizes and masses of many of the moons of Jupiter and Saturn are fairly well known due to numerous observations and interactions of the Galileo and Cassini orbiters; however, many of the moons with a radius less than ~100 km, such as Jupiter's Himalia, have far less certain masses. [5]
Cassini had its first flyby of Saturn's largest moon, Titan, on July 2, 2004, a day after orbit insertion, when it approached to within 339,000 km (211,000 mi) of Titan. Images taken through special filters (able to see through the moon's global haze) showed south polar clouds thought to be composed of methane and surface features with widely ...
Saturn's largest moon Titan appears to the upper left of Saturn. Saturn will be one of the evening sky objects to be observed with telescopes at a free public viewing session in Stedman on Nov. 16 ...
