Mars Facts
When the solar system settled into its current layout about 4.5 billion years ago, Mars formed when gravity pulled swirling gas and dust in to become the fourth planet from the Sun. Mars is about half the size of Earth, and like its fellow terrestrial planets, it has a central core, a rocky mantle, and a solid crust.

6 FAQs about [Solar system stuff]
How did the Solar System form?
The mass at its centre collected to form the Sun and a flat disk of dust around it. This eventually formed the planets and other bodies of the solar system. The solar system consists of the Sun, planets, dwarf planets, moons, and numerous smaller objects such as comets and asteroids.
What planets are in the Solar System?
It includes the rocky inner planets Mercury, Venus, Earth and Mars; the gas giants Jupiter and Saturn; and the ice giants Uranus and Neptune. Between Mars and Jupiter is a collection of asteroids known as the asteroid belt, while beyond Neptune is where small icy bodies, like Pluto and comets, live. How old is our solar system?
How many planets are in the Solar System?
Our solar system has one star, eight planets, five officially named dwarf planets, hundreds of moons, thousands of comets, and more than a million asteroids. Learn about the planets in our solar system. The solar system has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
What are some interesting facts about our Solar System?
Our solar system is in one of the Milky Way galaxy’s spiral arms called the Orion Spur. 5. A Long Way Around Our solar system takes about 230 million years to orbit the galactic center. 6. Spiraling Through Space The Milky Way is a barred spiral galaxy. 7. Room to Breathe Our solar system has many worlds with many types of atmospheres. 8.
Which planets are kept in orbit by the Sun?
The large mass of the sun produces an enormous gravitational pull that keeps all the planets of the solar system in their orbits. Even dwarf planet Pluto (formerly the ninth planet outright), which is six billion kilometers (3,728,227,153 miles) away, is kept in orbit by the sun.
Why are there so many rocky bodies in our Solar System?
Other smaller leftover pieces became asteroids, comets, meteoroids, and small, irregular moons. The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed.
