Neptune is the last planet in the solar system because pluto is too small to be a planet.

And also that there was a rumour about pluto being a moon of some planet but then the gravity to hold the planetoid was too weak so thats how pluto became a planet but its too small so now neptune is known as the last planet on the solar system

I hope this helps you :)
