where is titan located in the solar system Titan orbits Saturn when was this moon discovered? 1655 and by whom? Christiaan Huygens which planet does this moon belong to? Saturn can you tell me one physical characteristic of this planet? It lacks a definite surface, though it may have a solid core. how many rings does this planet have? UNANSWERABLE did any ancients observe this planet? Yes, Babylonian astronomers observed and recorded the movements of Saturn. where was the discoverer of the moon from? The Hague what did he make his debut with? "Theoremata de quadratura" in the field of quadrature what is the climate like on the moon? Water ice has an extremely low vapor pressure, so the little water vapor present appears limited to the stratosphere. did the moon also have lakes? Yes did anyone try to explore this moon?

Pioneer 11 [SEP] Introduction
Pioneer 11 (also known as Pioneer G) is a robotic space probe launched by NASA on April 6, 1973 to study the asteroid belt, the environment around Jupiter and Saturn, solar wind and cosmic rays. It was the first probe to encounter Saturn and the second to fly through the asteroid belt and by Jupiter. Thereafter, "Pioneer 11" became the second of five artificial objects to achieve the escape velocity that will allow them to leave the Solar System. Due to power constraints and the vast distance to the probe, the last routine contact with the spacecraft was on September 30, 1995, and the last good engineering data was received on November 24, 1995.
