It's important to remember that there's no single, definitive order of planets in the entire universe. We only know about the planets in our own solar system, and even those are constantly being redefined as we learn more about them.

However, if you're asking about the order of planets in our solar system, starting from the Sun, it's:

1. Mercury

2. Venus

3. Earth

4. Mars

5. Jupiter

6. Saturn

7. Uranus

8. Neptune

Pluto used to be considered the ninth planet, but in 2006 it was reclassified as a dwarf planet.
