Titan is the only moon in the Solar System with an atmosphere denser than Earth's, with a surface pressure of 1.448 atm, [52]: 834 and it is one of only two moons whose atmospheres are able to support clouds, hazes, and weather—the other being Neptune's moon Triton.
In contrast, the Lunar distance (LD or ), or Earth–Moon characteristic distance, is a unit of measure in astronomy. More technically, it is the semi-major axis of the geocentric lunar orbit . The lunar distance is on average approximately 385,000 km (239,000 mi), or 1.28 light-seconds ; this is roughly 30 times Earth's diameter or 9.5 times ...

Despite brisk temperatures of -290 degrees F, Saturn's giant Titan moon is of great interest to scientists, thanks to Earth-like geography, hydrocarbon "lakes" and even possible life. Though NASA ...
NASA's Orion spacecraft has shared a dramatic photo of the Earth and the Moon in a single shot. ... maximum distance from Earth of 268,563 miles. That's the farthest any human-oriented spacecraft ...
For the giant planets, the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure. [ 11 ] Because Sedna and 2002 MS 4 have no known moons, directly determining their mass is impossible without sending a probe (estimated to be from 1.7x10 21 to 6.1×10 21 kg for Sedna [ 12 ] ).
At a distance of 166.28 AU (24.9 billion km; 15.5 billion mi) from Earth as of December 2024, [4] it is the most distant human-made object from Earth. [5] The probe made flybys of Jupiter , Saturn , and Saturn's largest moon , Titan .
In order to be considered a "mini-moon," an incoming object must reach Earth at a range around 2.8 million miles and at a steady space of about 2,200 mph, according to Marcos.
