Components Of The Solar System

The solar system is a gravitationally bound system of the Sun, eight planets, dwarf planets, and many moons, asteroids, comets and meteoroids. It is located in the Milky Way galaxy.

The Sun

The Sun is a star, a hot ball of glowing gases that emits its own light and heat. It is the center of the solar system and makes up 99.8% of the mass of the solar system. The Sun’s gravity holds the planets, dwarf planets, and other objects in orbit around it.

The Planets

The planets are large, round objects that orbit the Sun. There are eight planets in the solar system:

• Mercury is the closest planet to the Sun. It is a small, rocky planet with a thin atmosphere.
• Venus is the second planet from the Sun. It is a rocky planet with a thick atmosphere that traps heat, making it the hottest planet in the solar system.
• Earth is the third planet from the Sun. It is the only planet in the solar system known to support life. Earth has a thick atmosphere that contains oxygen, nitrogen, and other gases.
• Mars is the fourth planet from the Sun. It is a rocky planet with a thin atmosphere. Mars has two moons, Phobos and Deimos.
• Jupiter is the fifth planet from the Sun. It is a gas giant made mostly of hydrogen and helium. Jupiter has a thick atmosphere and a strong magnetic field.
• Saturn is the sixth planet from the Sun. It is a gas giant made mostly of hydrogen and helium. Saturn has a thick atmosphere, a strong magnetic field, and a prominent ring system.
• Uranus is the seventh planet from the Sun. It is a gas giant made mostly of hydrogen and helium. Uranus has a thick atmosphere, a strong magnetic field, and a unique ring system.
• Neptune is the eighth planet from the Sun. It is a gas giant made mostly of hydrogen and helium. Neptune has a thick atmosphere, a strong magnetic field, and a prominent ring system.

The Dwarf Planets

Dwarf planets are objects that are similar to planets but do not meet all of the criteria to be classified as a planet. There are five dwarf planets in the solar system:

• Ceres is the largest dwarf planet. It is located in the asteroid belt between Mars and Jupiter.
• Pluto is the second largest dwarf planet. It is located in the Kuiper Belt, a region beyond Neptune.
• Eris is the third largest dwarf planet. It is located in the scattered disc, a region beyond the Kuiper Belt.
• Haumea is the fourth largest dwarf planet. It is located in the Kuiper Belt.
• Makemake is the fifth largest dwarf planet. It is located in the Kuiper Belt.

The Moons

Moons are natural satellites that orbit planets. There are over 200 moons in the solar system. The largest moon is Jupiter’s moon Ganymede, which is larger than the planet Mercury.

The Asteroids

Asteroids are small, rocky objects that orbit the Sun. There are millions of asteroids in the solar system, most of which are located in the asteroid belt between Mars and Jupiter.

The Comets

Comets are icy objects that orbit the Sun. When a comet approaches the Sun, its ice vaporizes and forms a tail that points away from the Sun.

The Meteoroids

Meteoroids are small, rocky objects that orbit the Sun. When a meteoroid enters the Earth’s atmosphere, it is heated by friction and glows, creating a meteor. If the meteoroid does not completely vaporize, it can land on the Earth’s surface as a meteorite.

Planets

Planets are large, round objects that orbit the Sun. They are made of rock and metal and have gravity. There are eight planets in the solar system:

• Mercury is the closest planet to the Sun. It is a small, rocky planet with a thin atmosphere.
• Venus is the second planet from the Sun. It is a rocky planet with a thick atmosphere that traps heat, making it the hottest planet in the solar system.

• Saturn is the sixth planet from the Sun. It is a gas giant made mostly of hydrogen and helium. Saturn has a thick atmosphere, a strong magnetic field, and a beautiful ring system.
• Uranus is the seventh planet from the Sun. It is a gas giant made mostly of hydrogen and helium. Uranus has a thick atmosphere, a strong magnetic field, and a unique ring system.
• Neptune is the eighth planet from the Sun. It is a gas giant made mostly of hydrogen and helium. Neptune has a thick atmosphere, a strong magnetic field, and a beautiful ring system.

Dwarf Planets

Dwarf planets are objects that are similar to planets but do not meet all of the criteria to be classified as planets. There are five dwarf planets in the solar system:

• Ceres is the largest dwarf planet. It is located in the asteroid belt between Mars and Jupiter.
• Pluto is the second largest dwarf planet. It is located in the Kuiper Belt, a region beyond Neptune.
• Eris is the third largest dwarf planet. It is located in the scattered disc, a region beyond the Kuiper Belt.
• Haumea is the fourth largest dwarf planet. It is located in the Kuiper Belt.
• Makemake is the fifth largest dwarf planet. It is located in the Kuiper Belt.

Moons

Moons are natural satellites that orbit planets. There are over 200 moons in the solar system. Some of the largest moons include:

• Ganymede is the largest moon in the solar system. It orbits Jupiter.
• Titan is the second largest moon in the solar system. It orbits Saturn.
• Callisto is the third largest moon in the solar system. It orbits Jupiter.
• Io is the fourth largest moon in the solar system. It orbits Jupiter.
• Europa is the fifth largest moon in the solar system. It orbits Jupiter.

Asteroids

Asteroids are small, rocky objects that orbit the Sun. There are millions of asteroids in the solar system. Most asteroids are located in the asteroid belt between Mars and Jupiter.

Comets

Comets are icy objects that orbit the Sun. Comets have a head, a coma, and a tail. The head is the solid nucleus of the comet. The coma is a cloud of gas and dust that surrounds the head. The tail is a stream of gas and dust that trails behind the comet.

Meteoroids

Meteoroids are small pieces of rock or metal that orbit the Sun. Meteoroids can range in size from a grain of sand to a boulder. When a meteoroid enters the Earth’s atmosphere, it is heated by friction and glows. This is what we see as a meteor, or shooting star. If a meteoroid does not completely vaporize in the atmosphere, it will land on the Earth’s surface. This is called a meteorite.
