Are there 7 moons?

The “Big Seven” refers to the largest moons in the solar system. The Big Seven are larger than all other moons in the solar system by a significant margin. They are, in descending order of size: Ganymede (Jupiter), Titan (Saturn), Callisto (Jupiter), Io (Jupiter), Luna (Earth), Europa (Jupiter), and Triton (Neptune).

Does Titan have seasons?

Titan experiences seasons as it makes its 29-year orbit around the Sun along with Saturn. Each of the four seasons lasts about seven Earth years so seasonal changes are expected to be very slow. The most recent seasonal switch occurred in 2009, when summer transitioned to autumn in the southern hemisphere.
