The Solar System
The Solar System. The Solar System is the assembly formed by the Sun, eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus & Neptune), their moons and other minor planets. Mercury. Mercury is named for the Greco-Roman messenger of the gods. He was very fast, and Mercury has the shortest and fastest orbit around the sun.
Jupiter
Jupiter is the largest planet in our solar system. If Jupiter was a hollow shell, 1,000 Earths could fit inside. Jupiter also is the oldest planet, forming from the dust and gases left over from the Sun''s formation 4.5 billion years ago. But it has the shortest day in the solar system, taking only 10.5 hours to spin around once on its axis.

In fact, the Olympus Mons is the largest volcano in our solar system. Since Mars is farther from the Sun than us, it takes longer to complete one revolution. It orbits the Sun in 687 Earth days. Mars has an atmosphere but it is very thin. Inhaling it would be toxic to us since it is largely composed of carbon dioxide, argon, and nitrogen.

6 FAQs about [Description of our solar system]
What is the Solar System made up of?
Our solar system is made up of the sun and all the amazing objects that travel around it. The universe is filled with billions of star systems. Located inside galaxies, these cosmic arrangements are made up of at least one star and all the objects that travel around it, including planets, dwarf planets, moons, asteroids, comets, and meteoroids.
What is a small body in the Solar System?
Any natural solar system object other than the Sun, a planet, a dwarf planet, or a moon is called a small body; these include asteroids, meteoroids, and comets. Most of the more than one million asteroids, or minor planets, orbit between Mars and Jupiter in a nearly flat ring called the asteroid belt.
How many planets are in our Solar System?
Our solar system includes the Sun, eight planets, five officially named dwarf planets, and hundreds of moons, and thousands of asteroids and comets. Our solar system is located in the Milky Way, a barred spiral galaxy with two major arms, and two minor arms.
Where is our Solar System located?
Our solar system is located in the Milky Way, a barred spiral galaxy with two major arms, and two minor arms. Our Sun is in a small, partial arm of the Milky Way called the Orion Arm, or Orion Spur, between the Sagittarius and Perseus arms. Our solar system orbits the center of the galaxy at about 515,000 mph (828,000 kph).
How did the Solar System form?
The Solar System[ d ] is the gravitationally bound system of the Sun and the objects that orbit it. [ 11 ] It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.
What are the different types of objects in the Solar System?
Traditionally, the solar system has been divided into planets (the big bodies orbiting the Sun), their satellites (a.k.a. moons, variously sized objects orbiting the planets), asteroids (small dense objects orbiting the Sun) and comets (small icy objects with highly eccentric orbits).
