Gasses & dust including all known elements.
It is called a "planetary system" or "solar system" (the latter term is used alone or capitalized to mean the Sun's system of planets, moons, asteroids, meteoroids, and comets).
They may both vary in sizes but are smaller than a planet. There are a lot of them. They hit large objects like planets, moons or stars often.
There is no reason to believe that he "won't ever" have more moons. On the contrary, it is quite possible that the gas giants - like Saturn - have gravitationally captured some asteroids, converting them into their moons - and this may happen again.
NO! A solar system is a star or star pair with things like planets, moons, asteroids, meteors, and dwarf planets orbiting around that star or star pair. In OUR solar system we have only one star, "The Sun".
Asteroids and Comets
its the comets are smaller than planets, moons, and asteroids. In order of size, usually comets < asteroids < moons < planets
The Sun, planets, moons, planetoids, asteroids, dust, gas, comets.
There are asteroids, meteoroids and comets.
Comets
Planets, moons, and asteroids, comets and gases, dust, particles etc.
Hydrogen gas has the least mass in the solar system.
The Solar System refers to the Sun and the planets (and their moons) and the other bodies that orbit it... including the asteroids, meteoroids and comets.
Basically absence... also comets, meteors, asteroids, planets, moons, satellites, shuttles and space stations, planets and moons.
No. There are more than that. There are currently 173 known moons orbiting planets in our solar system and many more orbiting dwarf planets, asteroids, and comets.
he solar system is made up of the sun at the center and all of the planets and their moons. as wel as a variety of asteroids and comets.
A solar system is a gravitational field within a galaxy consisting of a star and its satellite bodies such as planets, moons, asteroids, and comets.
