yes but they are outside our solar system in our Solar system are only 8 the others are dwarf planets

There are 11 in our close range solar system but millions outside our univerese or solar system. Remember space is infinite.
Many of the planets have more than one element. Two of these planets that have more than one element are Earth and Jupiter.
Most of the known extrasolar planets are more massive than Earth because massive planets are easier to detect. We have detected planets smaller than Earth.
Large planets have more gravity than smaller ones
The gas planets have more moons. Of all the gas planets non has fewer than 14 moons. Of the rocky planets, none has more than two. Mercury and Venus have none at all.
No, there is more hydrogen on the Jovian planets then the terrestrial ones.
No, the outer planets are not lighter than the inner planets. In fact, the outer planets are generally much larger and more massive than the inner planets. This is because they are primarily composed of gases and ice, which makes them less dense but more massive.
No. The Jovian planets are much more massive than the terrestrial planets.
None no planets have more moons than jupiter and jupiter has atleast 63 moons more than any other planet
Yes. 200 billions stars and 8 planets in our solar system.
Terrestrial planets have proportionately more silicate materials than Jovian ones.
Neptune has 11 moons. That's the nearest, but it has 13 known moons.
The gassy planets are much more massive than the inner planets, which means that have stronger more far-reaching gravitational fields. That in turn makes them more likely to capture odd collections of rock in the solar system.
