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.
