There are actually only eight planets in our solar system, and they are all closer to the sun than any other celestial body. Here they are in order from closest to furthest:

1. Mercury

2. Venus

3. Earth

4. Mars

5. Jupiter

6. Saturn

7. Uranus

8. Neptune

It seems you might be thinking of the dwarf planet Pluto, which was previously considered the ninth planet. Pluto is indeed further from the sun than Neptune, but it's no longer classified as a planet.
