Small & cold.
neither. Europa is not a planet, but one of Jupiters moons.
Jupiter is more massive then Venus, so Jupiter has more gravity. (the more massive a planet is, the more gravitational force it has on other objects)

The Suns mean density is around 1.41 g/cm3, which is similar to Jupiters density of 1.33 g/cm3 and Uranus' density of 1.30 g/cm3.
The planet Neptune was discovered in 1846.
Jupiters orbit is a imaginary circle that the planets circle around that is how we count years.

Europa is Jupiters moon.
At this time (mid-2014), 67 moons of Jupiter are confirmed. They are all in orbits around the planet. None are 'on' it.
Jupiter is the fifth planet from the Sun.
Jupiter is more massive then Venus, so Jupiter has more gravity. (the more massive a planet is, the more gravitational force it has on other objects)
The planet Mercury was discovered around 3,500 years ago, Unfortunately the name of the person who discovered it was not recorded.
What is planet Jupiter's rotation on axis time
Europa is one of Jupiters moons. Jupiter has many moons, but Europa is one of the four large moons that was discovered in 1610 by Galileo Galilei (and possibly independently by Simon Marius around the same time).
Jupiters density is around 1.33 g/cc on average, less dense than Earth and the other inner planets, but much more massive overall. Diameter of Jupiter (at the equator) is around 88,847 miles (compared to 7926 miles for the earth). Jupiters circumference at the equator is around 449,202 miles (compared with 40,075 miles for the earth). Jupiters volume is 1321 times that of Earths.
The first extra-solar planet (in other words, circling a star and not our sun) was discovered in 1995.
