Dwarf planets, moons and other objects
Asteroids
Asteroids are large rocky bodies that mostly orbit between Mars and Jupiter in an area called the asteroid belt. The largest asteroid in the region is called Vesta, and it is 328 miles (530 kilometers) wide.
Comets
Comet are called "Dirty snowballs" because they are made of frozen water, gas and dusk. A really famous comet, named Halley, is visible to the Earth every 75-76 years.
Dwarf planets
Dwarf planets are big enough to be shaped like spheres but too small to push smaller space objects out of their orbits. Four other space objects are also considered dwarf planets are Ceres, Eris, Haumea, and Makemake.
Pluto was considered a planet before, but in 2006, scientists downgraded it to dwarf planet.
Moons
Moons are natural satellites. They orbit planets and asteroids all over our solar system. There are about 200 moons in the solar system. Almost every major planets have moons, except for Venus and Mercury.
Planets and the Sun
Outer planets
Jupiter
-
It had rings, although really faint.
-
-
Neptune
80% of this planet is made of a hard dense fluid of icy material-water, methane and ammonia-above a small rocky core.
-
Uranus
It's the coldest planet in the solar system, although it's closer to the sun than Neptune

-
Inner planets
-
Venus
Second brightest object from Earth view, after the moon.

Formation
- A big cloud of gas began to spin and collapse
- At the center, gravity pulls a bunch of matters into it until it grew larger and larger
- Because the core is big, it began to compress it's particles together. The particles, called atoms, became so hot that they joined together in a process called fusion. This gave birth to the sun.
- Around the sun, planets began to be made. They are sphere because of the gravity. Because the sun used up almost all the matter, fusion could not occur. These soon became planets, dwarf planets and moons. The matters that did not form too big became meteoroids, asteroids and comets.
