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. [3]
The spacecraft will perform a gravity assist flyby of Earth to gain additional velocity on its way to Titan. [49] The spacecraft would be the first dedicated outer solar system mission to not visit Jupiter, as it will not be within the flight path.
The probe contained a DVD with more than 616,400 signatures from citizens in 81 countries, collected in a public campaign. [46] [47] Until September 2017 the Cassini probe continued orbiting Saturn at a distance of between 8.2 and 10.2 astronomical units (1.23 × 10 9 and 1.53 × 10 9 km; 760,000,000 and 950,000,000 mi) from the Earth.

Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin [4] [5] based on its characteristics; also known by its Kepler object of interest designation KOI-7016.01) is a candidate [6] [7] super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope.
Titan is the only object in the outer Solar System where a spacecraft has landed and conducted surface operations. The geology of Titan encompasses the geological characteristics of Titan, the largest moon of Saturn. Titan's density of 1.881 g/cm 3 indicates that it is roughly 40–60% rock by mass, with the rest being water ice and other ...
