Our solar system consists of the Sun, eight planets, numerous moons, dwarf planets, asteroids, and comets. It is a vast and fascinating place, constantly revealing new insights through scientific exploration.

The Sun

The Sun is the center of our solar system and by far its largest component, containing more than 99.8% of the total mass. It is a yellow dwarf star, about 4.6 billion years old, and provides the light and heat essential for life on Earth.

The Planets

The eight planets in our solar system, in order of increasing distance from the Sun, are:

• Mercury: The smallest planet and closest to the Sun.
• Venus: Known for its extremely hot and toxic atmosphere.
• Earth: Our home planet, unique for its abundant liquid water and diverse life.
• Mars: Often called the "Red Planet" due to its iron-rich surface.
• Jupiter: The largest planet, a gas giant with a prominent Great Red Spot.
• Saturn: Famous for its stunning system of rings.
• Uranus: An ice giant with a distinctive blue-green hue.
• Neptune: The outermost planet, also an ice giant.

Inner Planets

The inner planets are terrestrial planets, meaning they are primarily composed of silicate rocks or metals. They are generally smaller, denser, and have solid surfaces.

Outer Planets

The outer planets are gas giants (Jupiter and Saturn) or ice giants (Uranus and Neptune), characterized by their massive size, low density, and lack of solid surfaces.

Other Celestial Bodies

Beyond the planets, our solar system is home to:

• Dwarf Planets: Ceres, Pluto, Haumea, Makemake, and Eris are recognized dwarf planets.
• Asteroids: Rocky bodies orbiting the Sun, primarily found in the asteroid belt between Mars and Jupiter.
• Comets: Icy bodies that release gas and dust as they approach the Sun, forming a visible tail.
• Moons: Natural satellites that orbit planets and dwarf planets.
