Overview
Our solar system comprises eight major planets, as defined by the International Astronomical Union (IAU). These planets, in order from closest to farthest from the Sun, are:
- Mercury
- Venus
- Earth
- Mars
- Jupiter
- Saturn
- Uranus
- Neptune The planets can be categorized into several groups based on their composition and characteristics:
Terrestrial Planets
Mercury, Venus, Earth, and Mars are small, rocky planets with relatively thin atmospheres, primarily composed of rock and metal.
Giant Planets
Gas Giants
Jupiter and Saturn are the largest planets, primarily composed of hydrogen and helium gases with dense atmospheres.
Ice Giants
Uranus and Neptune are composed mainly of low-boiling-point materials such as water, methane, and ammonia, with thick atmospheres of hydrogen and helium. All planets orbit the Sun in the same direction and approximately in the same plane, following nearly circular orbits. Their sizes and masses vary significantly, with Jupiter being the largest (diameter: 139,822 km) and Mercury the smallest (diameter: 4,879 km). In addition to the major planets, the solar system includes dwarf planets (e.g., Pluto, Eris), moons, asteroids, comets, and meteoroids. The prevailing theory of planet formation is the nebular hypothesis, suggesting that planets form from the collapse of an interstellar cloud into a protostar surrounded by a protoplanetary disk. Each planet has unique features:
- Venus: Hottest planet due to its thick atmosphere causing a greenhouse effect
- Earth: Only known habitable planet with diverse surface and moderate atmosphere
- Mars: Home to the largest volcano in the solar system, Olympus Mons
- Jupiter: Strong magnetic field and more than double the mass of all other planets combined
- Saturn: Most moons among the planets
- Uranus and Neptune: Ice giants with thick atmospheres and unique compositions

History
The formation and history of our solar system, including Earth and its moon, can be summarized as follows:
Formation of the Solar System
Approximately 4.6 billion years ago, a gigantic cloud of dust and gas known as the solar nebula collapsed, likely triggered by a shock wave from a nearby supernova explosion. This event marked the beginning of our solar system's formation.
Formation of the Sun and Planets
The Sun formed at the center of the solar nebula, while planets formed in a thin disk orbiting around it through a process called accretion. In the inner solar system, Mercury, Venus, Earth, and Mars formed primarily from rocks and metals due to high temperatures. The outer planets (Jupiter, Saturn, Uranus, and Neptune) formed in cooler regions, accumulating gases and ices.
Formation of Earth and the Moon
Earth formed around 4.54 billion years ago through the accretion of dust and gas. A giant impact with a Mars-sized object called Theia led to the formation of the Moon. This collision vaporized rock and metal from both bodies, forming a disc around Earth that eventually cooled and clumped together to create the Moon.
Early Earth and Moon
The early Earth was largely molten due to frequent collisions and extreme volcanism. As the surface cooled, a solid crust formed, allowing liquid water to exist. The Moon's formation occurred shortly after Earth's crust first solidified. The first larger pieces of continental crust appeared around 4.0 billion years ago.
Late Heavy Bombardment
Between 4.1 and 3.8 billion years ago, a period known as the Late Heavy Bombardment occurred. Small worlds and meteorites bombarded the inner planets, delivering water and organic materials to Earth and causing widespread volcanism.
Evolution of the Solar System
Over billions of years, the solar system continued to evolve. The orbits of the planets stabilized, and the solar wind cleared out most of the remaining gas and dust. Smaller bodies like asteroids, comets, and Kuiper Belt objects were either ejected or remained in their current orbits.
Life on Earth
Life on Earth is believed to have begun around 3.8 billion years ago, during the Archean eon. The evolution of photosynthetic organisms around 2.5 billion years ago significantly altered Earth's atmosphere by introducing oxygen, paving the way for the diverse life forms we see today.
