It was once expected that any icy body larger than approximately 200 km in radius was likely to be in hydrostatic equilibrium (HE). [7] However, Ceres (r = 470 km) is the smallest body for which detailed measurements are consistent with hydrostatic equilibrium, [ 8 ] whereas Iapetus (r = 735 km) is the largest icy body that has been found to ...
Frequently described as a planet-like moon, Titan is 50% larger in diameter than Earth's Moon and 80% more massive. It is the second-largest moon in the Solar System after Jupiter's Ganymede and is larger than Mercury; yet Titan is only 40% as massive as Mercury, because Mercury is mainly iron and rock while much of Titan is ice, which is less ...
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.
Saturn's largest moon has been fully mapped for the first time.
Huygens (/ ˈ h ɔɪ ɡ ən z / HOY-gənz) was an atmospheric entry robotic space probe that landed successfully on Saturn's moon Titan in 2005. Built and operated by the European Space Agency (ESA), launched by NASA, it was part of the Cassini–Huygens mission and became the first spacecraft to land on Titan and the farthest landing from Earth a spacecraft has ever made.

The multi-mission radioisotope thermoelectric generator of Mars Science Laboratory, sent to the surface of Mars to power that robotic rover Dragonfly is designed as a rotorcraft lander, much like a large quadcopter with double rotors, which is known as an octocopter. [ 3 ]
Titan Saturn System Mission (TSSM) was a joint NASA–ESA proposal for an exploration of Saturn and its moons Titan and Enceladus, [1] where many complex phenomena were revealed by Cassini. TSSM was proposed to launch in 2020, get gravity assists from Earth and Venus , and arrive at the Saturn system in 2029.
