Google says: Europa's water would form a sphere 1,090 miles (1,754 km) in diameter. Earth's water-sphere would be 860 miles (1,384 km) across. Europa's ocean is 10 times deeper than the seas of Earth.

| With the average depth of Earth's oceans being roughly 14,000 feet, comparing that to the distance from the surface to the core makes it look incredibly shallow. Europa may be smaller than the moon, but it's primarily composed of water and water ice in the first place. |

yeah but like
140,000 feet of water straight down
dang that's a lot of pressure |

"alot of pressure"
Actually, not really. Europa's gravitational pull is a fraction of that on Earth, So the pressure will be fairly tame for most of the way down. |

Fun Fact: Dark Matter keeps all the Galaxies together. Without it, the galaxies would collapse and fall apart. Thank goodness for Dark Matter! Sources : Watching Sci Channel on Fridays

| No no no, there is the gravity holding Europa to jupiter and then there is Europas own gravity. If jupiter's gravity were to even slightly affect Europa, it would be pulled in my now. |

Errr no. Jupiter exerts tidal forces on Europa, but does not "lend" it gravity.

There is also water on other moons like Ganymede.

"Errr no. Jupiter exerts tidal forces on Europa, but does not "lend" it gravity."
that's not what i said
but wait i have another question
would the gravity from jupiter make it easier or harder to swim where water exists furthest from the core |

It wouldn't make a difference. It depends on Europa's gravity.

| Jupiter influences Europa by stretching it slightly. Europa tends to have slight bulges as it nears it's closest approach, and shrinks back when it extends out to the farthest portion of it's orbit. So assuming you could drill all the way down and start swimming in the subsurface oceans, there could be currents produced by the relationship between the moon and the parent planet. |

True. That is also the reason why there may be life on Europa. Jupiter's gravity pulls on Europa's core, heating it up, and possible creating underwater thermal vents that could warm the water, making life possible

| If we ever need to go there, just send a satellite with an oil drum on it and tell the President once it arrives. |

but oil can't melt ice sheets |
