For example, Titan looks bigger than Ganymede, but its solid body is smaller. For the giant planets , the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure.
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.
Human-made objects orbiting the Sun, Mercury, Venus, Earth, Mars, and Saturn, including active artificial satellites and space junk; Heliosphere, a bubble in space produced by the solar wind Heliosheath. Heliopause; Hydrogen wall, a pile up of hydrogen from the interstellar medium
Titan has a surface gravity of 0.138 g, slightly less than the Moon. Managing long-term effects of low gravity on human health [8] would therefore be a significant issue for long-term occupation of Titan, more so than on Mars. These effects are still an active field of study.
Astronomers believe the mysterious “magic islands” on Saturn’s moon Titan are honeycomb-like frozen clumps of organic material that fall like snow on the moon.
The atmosphere of Titan is the dense layer of gases surrounding Titan, the largest moon of Saturn.Titan is the only natural satellite of a planet in the Solar System with an atmosphere that is denser than the atmosphere of Earth and is one of two moons with an atmosphere significant enough to drive weather (the other being the atmosphere of Triton).

Mimas is the seventh-largest moon of Saturn, which all told has well over 100 moons ranging from Titan - larger than the planet Mercury - to some only the size of a city block.
Viewers in most of the continental United States, eastern Canada, and parts of Africa and Mexico can look for a celestial triangle in the sky when evening twilight ends at 6:11 p.m. ET. Mars will ...
