Meteorites or asteroids can strike planets and moons.
ff
The rings are mainly made of from dust, ice or rubble from that planet.Most moons are asteroids or bits of the planet that have broken off of the planet caught in the gravitational pull from the planet.
Made of rock and have few or no moons.
Saturn has rings of ice and rocks and at least 18 moons
Each of the four outer gas giant planets has several moons and each of them also has a ring system which is made up of dust particles and rocks. These four outer planets are Jupiter, Saturn, Uranus and Neptune.
meteors
the solar system is made up with space rocks, stars, moons, and planets.
moons are usually lumps of rocks caught in a planets gravitational pull planets can be made of gas and have to be a certain(Pluto is no longer a planet because it is too small)
Pieces of rocks made of minerals similar to those that are formed the rocky planets and moons.
Most but not all larger MOONS (bodies that orbit planets, moons, or asteroids) accreted in the same way that PLANETS did, assuming a variable density and a nearly spherical shape. Very large moons such as Titan have many of the characteristics of planets: vulcanism, atmospheres, and weather. Generally speaking, moons orbit planets in the same way that planets orbit stars.
yes they are. when the planets were first made, they crashed together and the astroids broke off the planets
"Moons" can be made of rocks, water, ice, methane ice, ethane ice, dust, sulfur, volcanoes, and so forth. The planets Mercury, Venus, Earth, and Mars are made of many of the same things, with the possible exception of the methane and ethane ices.
The rings are mainly made of from dust, ice or rubble from that planet.Most moons are asteroids or bits of the planet that have broken off of the planet caught in the gravitational pull from the planet.
Most of the gasses were swept out of the inner solar system by the solar wind, leaving rock as the most abundant material to form planets and moons.
A moon. Of course planets may have different numbers of moons - Mercury and Venus have no moons, the Earth has one, Mars has two, Jupiter has more than 60, etc.
Because god made them that way
Terrestrial Planets are made up of rocks and minerals! They are very rocky and some of them are icy! but they are mostly made up of rocks.
All the inner planets are rocky or terrestrial planets.
