Titan is Saturn’s largest moon and the second largest moon in our solar system. Titan is special because it is the only moon we have observed that has a thick atmosphere with clouds.
Titan is the largest moon of Saturn and the second largest moon in our solar system. The only moon larger is the Jovian moon, Ganymede. Titan is 50% larger than our Moon and larger than the planet Mercury. Titan is composed of ice and rock. Titan is of particular interest to scientists as it is the only moon with a dense atmosphere and clouds. Its atmosphere is composed of nitrogen and methane, with traces of other hydrocarbons.
Titan was discovered by the Dutch astronomer Christiaan Huygens after he was inspired by the discovery of the four Jovian moons by Galileo Galilei. He discovered the moon on March 25, 1655 making it the sixth moon ever discovered. The moon was originally named after a number, but was renamed Titan by John Herschel after the Greek divine being.
Titan is tidally locked to Saturn, like our own Moon, meaning that one side faces Saturn as it orbits the planet. This also makes its orbital period the same as its rotational period: Titan's day is the same length as its year. Scientists have found rivers and lakes of a liquid on the moon. The surface is far too cold for liquid water to exist. Scientists think that these bodies of liquid could be composed of liquid hydrocarbons.
The Hubble space telescope took the first recorded pictures of the moon. It was difficult to observe the moon due to the thick clouds that covered the surface. The first visit by a probe to the Saturn system was Pioneer 11 in 1979. In 1997, NASA launched a Cassini spacecraft to investigate further. Cassini took nearly seven years to reach the Saturn system. It was sent there to study Saturn, its rings, and Saturn’s moons. Part of the mission was to release a lander onto Titan. The spacecraft released the European-built Huygen probe, which fell through the Titan atmosphere. Its descent took two and a half hours in total, and was the first spacecraft to land in the outer solar system.

How Tos about Saturn's Moon Titan
How to Create a Classroom Model of Titan’s Surface Features
Build a hands-on model of Titan’s landscapes to help students visualize and engage with Saturn’s largest moon.
Gather materials like clay, sand, and blue cellophane
Collect simple supplies such as modeling clay for land, sand for dunes, and blue cellophane to represent methane lakes.
Research Titan’s main surface features as a class
Guide students as they identify and describe key features like lakes, dunes, and craters using books or trusted websites.
Shape the landscape on a tray or cardboard base
Have small groups sculpt mountains, smooth out plains, and add lakes and dunes to their models using the gathered materials.
Label each feature and present to the class
Ask students to create labels for surface features and explain what they represent, reinforcing science vocabulary and understanding.
Frequently Asked Questions about Saturn's Moon Titan
What is Titan, the moon of Saturn?
Titan is the largest moon of Saturn and the second-largest natural satellite in our solar system. It is known for its thick, nitrogen-rich atmosphere and lakes of liquid methane and ethane.
How is Titan different from Earth's moon?
Titan has a dense atmosphere and surface lakes of hydrocarbons, while Earth's moon has almost no atmosphere and a dry, rocky surface. Titan is also larger and colder than our moon.
Why is Titan important to scientists?
Titan is important because its atmosphere and surface chemistry may be similar to early Earth. Studying Titan helps scientists understand how planets and moons evolve, and it may offer clues about the possibility of life elsewhere.
What are some interesting features of Titan?
Titan has rivers, lakes, and seas made of liquid methane and ethane, sand dunes, icy volcanoes (cryovolcanoes), and a thick orange haze that covers its surface.
Can humans live on Titan?
Humans cannot currently live on Titan because it is extremely cold (about -290°F or -179°C) and lacks oxygen. However, its thick atmosphere could help protect future explorers from harmful space radiation.
