You're asking about the order of the planets in our solar system, not the Milky Way galaxy. The Milky Way is a vast spiral galaxy containing billions of stars, including our Sun and its planetary system.
Here's the correct order of the planets in our solar system, starting from the Sun:
1. Mercury
2. Venus
3. Earth
4. Mars
5. Jupiter
6. Saturn
7. Uranus
8. Neptune
This order is determined by their distance from the Sun.
