Major planets in the solar system
ESA
The Solar System is made up of the Sun and all of the smaller objects that move around it. Apart from the Sun, the largest members of the Solar System are the eight major planets. Nearest the Sun are four fairly small, rocky planets - Mercury, Venus, Earth and Mars. Beyond Mars is the asteroid belt – a region populated by millions of rocky
The Characteristics of the Eight Planets
Further from the sun, past a ring of asteroids, lies the largest planet in our solar system — Jupiter — the first of the gas giant planets. Its characteristic colored cloud patterns are caused by enormous, swirling storms in its atmosphere, which consists of primarily of hydrogen, helium, methane ammonia and water ice.

While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal. Namesake. Namesake. The name Earth is at least 1,000 years old.
Planets – classification, primary planets, dwarf planets, comparison
Planet classification. There are four main categories of classifications when determining the type of celestial body an object is. These classifications are: terrestrial planets (Mercury, Venus, Earth, and Mars), gas giants (Jupiter and Saturn), ice giants (Uranus and Neptune), and dwarf planets (Pluto, Eris, Haumea, and Makemake).Ceres at this current time is still labeled as an asteroid
Mercury Facts | Information, History, Location, Size & Definition
- Mercury''s core has a higher iron content than that of any other major planet in the Solar System. - Your weight on Mercury would be 38% of your weight on Earth as Mercury has a gravity of 3.7 m/s², while Earth has 9.807 m/s². - The most cratered planet in the solar system is Mercury. - NASA has mapped the entire surface of Mercury.

The Different Types Of Planets
The Different Types Of Planets. Our solar system is home to eight planets, all of which are categorized between two different types of planet: rocky and gas giant.The four inner planets, Mercury, Venus, Earth, and Mars, are all rocky planets.Meanwhile, the four outer planets, Jupiter, Saturn, Uranus, and Neptune, are all gas giants.The vast majority of planets
Solar System
Solar system. The solar system comprises the Sun, nine major planets, some 100,0000 asteroids larger than 0.6 mi (1 km) in diameter, and perhaps 1 trillion cometary nuclei.While the major planets lie within 40 astronomical units (AU) of the Sun, the outermost boundary of the solar system stretches to 1 million AU, one third the way to the nearest star.
The Characteristics of the Eight Planets
The solar system has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. There are five officially recognized dwarf planets in our solar system: Ceres, Pluto, Haumea, Makemake, and Eris.
Solar System Facts | Information, Size, History and Definition
The planets of the outer solar system are Jupiter, Saturn, Uranus, and Neptune (Pluto is now classified as a dwarf planet): The first thing to notice is that the solar system is mostly empty space. The planets are very small compared to the space between them. Even the dots on the diagrams above are too big to be in proper scale with respect to

For a discussion of that action and of the definition of planet approved by the IAU, see planet. 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.

In Depth | Our Solar System – NASA Solar System Exploration
The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed. Nearest to the Sun, only rocky material could withstand the heat when the solar system was young. For this reason, the first four planets – Mercury, Venus, Earth, and Mars – are terrestrial planets.
Solar System
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.The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its
