Selected solar system

The solar system is the gravitationally bound system of the Sun and the objects that orbit it. The largest of such objects are the eight planets, in order from the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The terrestrial planets have a definite surface and are mostly made of rock and metal. The gas giants are mostly made of hydrogen and helium, while the ice giants are mostly made of 'volatile' substances such as water, ammonia, and methane.

The solar system was formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. Over time, the cloud formed the Sun and a protoplanetary disk that gradually coalesced to form planets and other objects. That is the reason why all eight planets have an orbit that lies near the same plane. In the present day, 99.86% of the Solar System's mass is in the Sun and most of the remaining mass is contained in the planet Jupiter. Six planets, the six largest possible dwarf planets and many other bodies have natural satellites or moons orbiting around them.

Here are the eight planets of the solar system, in order from the Sun:

Mercury: The smallest and closest planet to the Sun. It has no moons and a very thin atmosphere.

In addition to the planets, there are many other objects in the solar system, including:

Dwarf planets: These are objects that are smaller than planets but larger than asteroids. Pluto is the most famous dwarf planet.

Asteroids: These are small rocky bodies that orbit the Sun. They are mostly found in the asteroid belt, between the orbits of Mars and Jupiter.

Comets: These are icy bodies that orbit the Sun. When they get close to the Sun, they heat up and release a tail of gas and dust.

Meteoroids: These are small pieces of rock or metal that orbit the Sun. They can sometimes enter Earth's atmosphere and burn up as a shooting star.

The solar system is a vast and complex place, and we are still learning about it. There are many mysteries that remain to be solved, such as the origin of life and the possibility of other habitable planets.
