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.
Maybe it's because they have to be extra large to be discovered.
I think you mean extrasolar planets. Technically, all planets except Earth are "extraterrestrial." At last report there were almost 900 of them, with more to follow. They aren't a "group" in the usual sense, just a category.
Yes. The massive giant planets have far more moons than the less massive terrestrial planets.
The four inner, terrestrial or rocky planets all have similar densities, much higher than the four outer gas giant planets (though the outer planets are much larger and more massive).
The gas giants.

Most known extrasolar planets are more massive than Jupiter because they are easier to detect with current technology. More massive planets exert a stronger gravitational pull on their parent stars, causing a more noticeable wobble or dimming of light that can be detected. Smaller planets like Earth are harder to observe due to their smaller size and weaker gravitational influence.

Most known extrasolar planets least resemble Earth, both in terms of size and distance from their parent stars. Gas giants, hot Jupiters, and super-Earths are more common than small, rocky planets like Earth among the exoplanets discovered so far.
Inside our sollar system, the planets Jupiter, Saturn, Uranus and Neptune are all larger and more massive than Earth.
Earth
None of the planets that scientist know is exactly 15 times more massive than earth, but the closet one is Saturn, it is 18 times more bigger than earth,
Of what we have found most are the size of Jupiter or larger. But we know many more extrasolar planets exist that we simply cannot detect. If we were to draw hypotheses on what planets are most abundant they would either be similar to dwarf planets. Or, if the reader does not view dwarf planets as true planets then planets the size of ones in the terrestrial zone like: Mercury, Venus, or Earth. Are probably the most abundant.
More massive planets have more gravitational pull. If a satellite were to pass by Earth and Jupiter at the same distance from each planet, the satellite would be more attracted to start orbiting Jupiter because of its pull. The more massive a planet is the more likely it is to get a satellite to orbit it.
I don't think so. No official "planet" in the Solar System has such a weak gravity; most of the so-called "extrasolar" planets (i.e., outside our Solar System) are quite a bit more massive than Earth, since such planets are easier to discover.Other dwarf planets in the Solar System may have a weaker gravity, if you want to count those.
Jovian means Jupiter-like - these planets are made of gas and are several times more massive than the Earth - like Jupiter.
Massive is planets that orbit the sun and have more mass
