Saturn's moon, Titan

4.5 billion years, about the same age as Saturn


Solar system, in orbit around Saturn

Avg. distance from Saturn

1,221,830 km (759,000 mi)


5,150 km (3,200 mi)


1.3452 x 1023 kg

Orbital period around Saturn

15.9 days. The same side of Titan always faces Saturn. It takes the same amount of time to make one revolution on its axis as it does to complete an orbit around Saturn.

Distinguishing features

Titan is the largest moon of Saturn and the only known moon in the solar system with a dense atmosphere. Its atmosphere, primarily nitrogen, is more dense than Earth's atmosphere. The moon is composed of ice and rock. Explorations of Titan's surface by the Cassini-Huygens mission have revealed a lake of liquid methane.

How to use in the classroom

Use this resource as:

A source of information. Read the table to find out about this object.

A large-number recognition and ordering activity. Have students review several Fast Fact moon tables, including this one. Have students read the tables to find each object's mass. Then ask them to arrange the objects according to their mass, from smallest to largest. Students also can arrange the objects according to their diameter.

A math activity. Use Newton's law of gravitation, the distance between Io and Jupiter, and the masses of the two objects to determine the gravitational force between them. (Recommended for grades 10-12)

An inquiry tool. Have students write down questions they would like answered about the image and the information in the Fast Facts table.

An engagement tool. Involve students in a discussion.
