PIX4606094: Huygens probe lands on Titan. - Huygens probe lands on Titan. - Artist's view of the descent of the European probe Huygens on Titan. Huygens landed on the Titan satellite on 14 January 2005. The Cassini-Huygens probe was launched on 15 October 1997 and has been placed in orbit around Saturn since 1 July 200, Dixon, Don (b.1951) / Bridgeman Images
PIX4633504: The capture of the Moon - Moon capture theory - Infographic showing the different processes of capturing a satellite by a planet. At the top, the developing planetary halo of gas slows down and captures a passing Celestial body. In the middle, the sphere of gravitational influence of the planet develops and attracts a celestial body. At the bottom, interactions between passing asteroids can cause one to remain in orbit around a planet. Infographic shows processes for planet to aquire a satellite. A developing planet's halo of gas expands to capture a passing body (top). Its gravitational sphere of influence expands as well (middle). Interactions between passing asteroids may cause one to fall into orbit (bottom), Dixon, Don (b.1951) / Bridgeman Images
