Titan (moon) Trivia Questions

How much do you really know about Titan (moon)? Below are 8 true or false statements. Click each one to reveal the answer and explanation.

1.

You could walk on Titan without a spacesuit if you had an oxygen mask and warm clothing.

Click to reveal answer ›

Easy
✗ FALSE

Titan's surface is extremely cold (-290°F) and its atmosphere lacks oxygen. Even with an oxygen mask and heavy insulation, the cold would kill you quickly, and the pressure requires a suit.

2.

Titan's rivers and lakes are filled with liquid methane instead of water.

Click to reveal answer ›

Easy
✓ TRUE

Titan's surface temperature is around -290°F (-179°C), so water is rock-hard ice. Methane and ethane exist as liquids, forming rivers, lakes, and even rain.

3.

Titan's orange haze is caused by volcanic eruptions spewing sulfur compounds.

Click to reveal answer ›

Medium
✗ FALSE

Titan's orange haze comes from photochemical reactions in its upper atmosphere, where sunlight breaks down methane and nitrogen, creating complex organic particles (tholins). No sulfur volcanoes.

4.

Titan is larger than Mercury and has a thicker atmosphere than Earth.

Click to reveal answer ›

Medium
✓ TRUE

Titan is bigger than Mercury (about 50% larger in diameter) and its atmospheric pressure at the surface is 1.5 times that of Earth's, though it's mostly nitrogen.

5.

Titan is the only moon in the solar system with liquid lakes on its surface.

Click to reveal answer ›

Medium
✗ FALSE

Titan does have liquid methane and ethane lakes, but it's not the only moon—Saturn's moon Enceladus and Jupiter's Europa have subsurface liquid oceans, though not surface lakes.

6.

Titan's surface has dunes made of hydrocarbon sand, not silicate sand like Earth's.

Click to reveal answer ›

Hard
✓ TRUE

Radar images from Cassini revealed vast dunes around Titan's equator, composed of solid hydrocarbons (like benzene and other organics) that fell from the atmosphere as particles.

7.

Titan has a permanent underground ocean of liquid water, kept warm by tidal heating.

Click to reveal answer ›

Hard
✓ TRUE

Cassini data revealed a subsurface ocean of liquid water beneath Titan's icy crust, likely kept liquid by tidal forces from Saturn and possibly ammonia acting as antifreeze.

8.

Titan's atmosphere is so thick that you could fly through it by flapping wings strapped to your arms.

Click to reveal answer ›

Hard
✓ TRUE

Titan has a dense atmosphere and low gravity (about 1/7 of Earth's). A human with wing-like appendages could generate enough lift to fly, though it would be extremely cold.
