Physical Characteristics
Europa is slightly smaller than Earth's Moon. At just over 3,100 kilometres (1,900 mi) in diameter, it is the sixth-largest moon and fifteenth largest object in the Solar System. Though by a wide margin the least massive of the Galilean satellites, it is nonetheless more massive than all known moons in the Solar System smaller than itself combined. Its bulk density suggests that it is similar in composition to the terrestrial planets, being primarily composed of silicate rock.

Famous quotes containing the word physical:
“The author’s conviction on this day of New Year is that music begins to atrophy when it departs too far from the dance; that poetry begins to atrophy when it gets too far from music; but this must not be taken as implying that all good music is dance music or all poetry lyric. Bach and Mozart are never too far from physical movement.”
—Ezra Pound (1885–1972)
