Titan is the only moon that has an atmosphere, although it is not one that could support humans. Titan along with Enc Titan is larger than our smallest planet, Mercury. As part of Cassini-Huygens mission, the Huygens probe was launched into the atmosphere to discover more about the moon. The picture below is a photo from the Huygens space probe that took a photo of the environment.
Source: N.A.S.A.Titan is a Moon that orbits round Saturn rather than the Sun which our Earth orbits round. Its orbit circumference, the total distance it travels round its planetary parent is 7,675,612.02 km. The furthest it gets from its orbital parent (apoasis) is 1,257,055 km. Its mass is estimated/calculated at being 134,552,523,083,241,000,000,000 kg. Its density has been calculated at being 1.882 g/cm3. Its volume is 1.882 g/cm3. It was discovered in the year 1655 by C. Huygens.
The Semi-Major Axis of the orbit is 1,221,865 km, which is the furthest point from the centre to the edge of an elliptical point.
The atmospheric gases within the atmosphere of the object are N2, CH4. The temperature in at the surface is about 94 K.
The mass of the object is calculated at being 134,552,523,083,241,000,000,000 kg. The equatorial circumference of Titan is 16,177.5 km. The mean radius of Titan is 2,574.7 km. The surface area of Titan is 83,305,418.53 km2. The surface gravity of the said item is 1.354 m/s2. The average orbit velocity, that is the speed at which it orbits is 20,051.2 km/h.
The orbital inclination, the angle at which Titan orbits in relation to the orbital plane is 0.312 degrees. The orbital eccentricity is 0.0288, it is the degree at which Titan orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
