Which natural satellite in our solar system is as big as a planet in our solar system?

What-A-Mess

Titan and Ganymede. Titan (tye'-tən, IPA /ˈtaɪtn̩/, Greek Τιτάν) or Saturn VI is the largest moon of Saturn and the second largest moon in the solar system. Ganymede (gan'-ə-meed, IPA: [ˈgænəmid]; Greek Γανυμήδης) is Jupiter's largest moon, and indeed the largest moon in the entire solar system; it is larger in diameter than Mercury but only about half its mass. Ganymede is much larger than Pluto. Ganymede is the only planetary satellite (besides the Moon) that can be seen by the naked eye — but only with very good eyesight during ideal conditions. Calisto, Europa and Io may fit the bill as well. http://en.wikipedia.org/wiki/Image:Moons_of_solar_system_v2.jpg http://en.wikipedia.org/wiki/Image:Moons_of_solar_system_v2.jpg Jul 12 06, 10:43 AM

Thanks everyone. I think I'll go with the moon as the quiz I got this from seems quite a simplistic one. Jul 13 06, 2:36 AM
