The Solar System: A Beginner’s Guide to Our Cosmic Neighborhood
The solar system is the collection of celestial bodies bound by gravity to our Sun. It includes:
- Eight planets (including Earth)
- Over 200 moons
- Asteroids and comets
- Dwarf planets like Pluto
☀️ The Sun – Our Star
At the center lies the Sun, a massive ball of hydrogen and helium that provides energy for all life on Earth.
🪐 The Planets
The planets are divided into:
- Terrestrial Planets: Mercury, Venus, Earth, Mars
- Gas Giants: Jupiter and Saturn
- Ice Giants: Uranus and Neptune
🌌 How Did It Form?
The solar system formed around 4.6 billion years ago from a cloud of gas and dust. Gravity pulled this material into a spinning disk, where the Sun formed at the center, and planets formed in orbit around it.
This is our cosmic home—vast, complex, and still full of mysteries.
