What is the diameter of Europa?

Answer 1

Europa is a large moon of Jupiter. Its surface is made of ice, which may have an ocean of water beneath it. Europa's diameter is 1,940 miles or 3,122 kilometers, slightly smaller than Earth's moon. Europa takes 3.55 days to orbit Jupiter at a distance of 416,900 miles or 670,900 kilometers. The Italian astronomer Galileo discovered Europa in 1610. Much of what is known about it comes from data gathered by a space probe, also named Galileo, that orbited Jupiter from 1995 to 2003.

Answer 2

A bit of Math:

We'll assume that Jupiter is at it's closest point to Earth 4.2 AU = 628,320,000 km

Europa diameter is 1,569 km

So the angle in which we see it is sin-1(1569/628,320,000) = 0.000143075308849 degrees

This translates to 0.52 arc seconds.

Answer 3

Mass (kg) 4.8e+22 Mass (Earth = 1) 8.0321e-03 Equatorial radius (km) 1,569 Equatorial radius (Earth = 1) 2.4600e-01 Mean density (gm/cm^3) 3.01

Answer 4

The radius of Europa is 1,569 kilometers.

Therefore the circumference is 9,858 kilometers

Answer 5

It is about 3,100 kilometres or 1,900 miles in diameter.

Answer 6

Europa has a diameter of 1,569 km.

Answer 7

About 3120 km.
