Titan is similar to the very early Earth and can provide clues to how life may have arisen on Earth. In 2005, the European Space Agency's Huygens lander acquired some atmospheric and surface measurements on Titan, detecting tholins, [32] which are a mix of various types of hydrocarbons (organic compounds) in the atmosphere and on the surface.
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.

At inferior conjunction (for the terrestrial observer, this is the opposition of Mars and the Sun), the maximum visible distance between the Earth and the Moon would be about 25′, which is close to the apparent size of the Moon in Earth's sky. The angular size of Earth is between 48.1″ and 6.6″ and of the Moon between 13.3″ and 1.7 ...
Recently, NASA selected the SpaceX Falcon Heavy to launch the Dragonfly aerial probe to Titan, Saturn’s largest moon. The selection constitutes another win for Elon Musk’s launch company.

The size of solid bodies does not include an object's atmosphere. 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 was examined by both Voyager 1 and 2 in 1980 and 1981, respectively. Voyager 1's trajectory was designed to provide an optimized Titan flyby, during which the spacecraft was able to determine the density, composition, and temperature of the atmosphere, and obtain a precise measurement of Titan's mass.

NASA launched a robotic space lander bound for Mars on Saturday morning, beginning a journey to explore the deep interior of the red planet.
