Introduction to the Solar System

Solar System

The Solar System is our local neighborhood in space, containing the Sun and all objects that orbit it, including planets, moons, asteroids, comets, and meteoroids. The Solar System formed approximately 4.6 billion years ago from the gravitational collapse of a giant molecular cloud. The majority of the system's mass is contained in the Sun, with the vast majority of the remaining mass contained in Jupiter.

The Sun

Sun

The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma, radiating energy and light. The Sun's energy supports almost all life on Earth by driving photosynthesis, and is the source of climate and weather. The Sun is composed primarily of hydrogen, which it fuses into helium through nuclear fusion in its core, producing immense energy.

Planets of the Solar System

Planets

There are eight recognized planets in the Solar System, which are divided into two categories: terrestrial planets and gas giants. The terrestrial planets, which include Mercury, Venus, Earth, and Mars, are composed mostly of rock and metal. The gas giants, which include Jupiter, Saturn, Uranus, and Neptune, are composed mostly of hydrogen and helium.

Mercury

Mercury

Mercury is the smallest planet in the Solar System and closest to the Sun. It has a very thin atmosphere and surface temperatures that can reach up to 800 degrees Fahrenheit (427 degrees Celsius) during the day and drop to -330 degrees Fahrenheit (-201 degrees Celsius) at night.

Venus

Venus

Venus is the second planet from the Sun and similar in size and structure to Earth, but with a thick, toxic atmosphere that traps heat, making it the hottest planet in our Solar System. Surface temperatures can reach 900 degrees Fahrenheit (475 degrees Celsius).

Earth

Earth

Earth is the third planet from the Sun and the only known planet to support life. It has a diverse environment with oceans, forests, deserts, and polar regions. Earth's atmosphere contains 78% nitrogen and 21% oxygen, which supports life.

Mars

Mars

Mars, known as the Red Planet, is the fourth planet from the Sun. It has a thin atmosphere composed mostly of carbon dioxide and surface features reminiscent of both Earth and the Moon. Mars has the largest volcano in the Solar System, Olympus Mons, and a canyon system, Valles Marineris, that dwarfs the Grand Canyon.

Jupiter

Jupiter

Jupiter is the largest planet in the Solar System and fifth from the Sun. It is a gas giant with a mass more than twice that of all the other planets combined. Jupiter's atmosphere is known for its Great Red Spot, a giant storm that has been raging for hundreds of years.

Saturn

Saturn

Saturn is the sixth planet from the Sun and the second-largest in the Solar System. It is a gas giant known for its stunning ring system, which is composed of ice and rock particles. Saturn has numerous moons, including Titan, the second-largest moon in the Solar System.

Uranus

Uranus

Uranus is the seventh planet from the Sun and the third-largest in the Solar System. It is unique in that it rotates on its side, likely due to a massive collision early in its history. Uranus has a blue-green color due to methane in its atmosphere and has faint rings.

Neptune

Neptune

Neptune is the eighth and farthest known planet from the Sun. It is similar in composition to Uranus and is known for its intense blue color. Neptune has the strongest winds in the Solar System, with speeds reaching up to 1,200 miles per hour (2,000 kilometers per hour).
