Compare the relative size of a galaxy to our solar system

The relative size of a galaxy compared to our solar system is immense. To give you a clearer picture, let's break it down:
1. **Our Solar System**: The solar system consists of the Sun and everything bound to it by gravity, including eight planets (like Earth), their moons, dwarf planets, asteroids, comets, and other small celestial objects. The solar system spans a distance of about 100 astronomical units (AU) from the Sun to the furthest known dwarf planet, which is roughly 0.002 light-years or about 1 light-day.
2. **Galaxies**: Galaxies are vast collections of stars, gas, dust, and dark matter. The Milky Way galaxy, which is our home galaxy, has a diameter of about 100,000 light-years and contains hundreds of billions of stars.
To put this in perspective, if we imagine our solar system as a small marble about 1 centimeter in diameter, the Milky Way galaxy would be like a sphere with a diameter of around 1,000 kilometers (roughly 620 miles). This comparison illustrates just how small our solar system is in relation to the vast scale of a galaxy.
In summary, while our solar system is a relatively tiny part of the universe, galaxies like the Milky Way are massive structures containing billions of stars and their planetary systems, dwarfing the size of our solar system by many orders of magnitude.
