A montage of Jupiter and its four largest moons (distance and sizes not to scale) There are 95 moons of Jupiter with confirmed orbits as of 5 February 2024. [1] [note 1] This number does not include a number of meter-sized moonlets thought to be shed from the inner moons, nor hundreds of possible kilometer-sized outer irregular moons that were only briefly captured by telescopes.

To support an Earth-like atmosphere for about 4.6 billion years (Earth's current age), a moon with a Mars-like density is estimated to need at least 7% of Earth's mass. [20] One way to decrease loss from sputtering is for the moon to have a strong magnetic field of its own that can deflect stellar wind and radiation belts.
Europa (Jupiter II), the second of the four Galilean moons, is the second closest to Jupiter and the smallest at 3121.6 kilometers in diameter, which is slightly smaller than Earth's Moon. The name comes from a mythical Phoenician noblewoman, Europa , who was courted by Zeus and became the queen of Crete , though the name did not become widely ...
At 16:06 GMT, NASA launched the Europa Clipper ship from Cape Canaveral, Florida, to search for signs of life on one of Jupiter’s frozen moons. “Discovering life on other celestial bodies ...
NASA is set to launch a spacecraft to Jupiter's moon Europa, considered one of our solar system's most promising spots to search for life beyond Earth, to learn whether this ice-encased world ...
The James Webb Space Telescope has detected carbon, a building block of life, on the surface of Jupiter’s icy moon Europa.
Europa / j ʊ ˈ r oʊ p ə / ⓘ, or Jupiter II, is the smallest of the four Galilean moons orbiting Jupiter, and the sixth-closest to the planet of all the 95 known moons of Jupiter. It is also the sixth-largest moon in the Solar System .
The skies around Europa host waves that are "only" around 100 times more intense. "Chorus waves have been detected in space around the Earth but they are nowhere near as strong as the waves at ...
