Neptune


Neptune is the eighth and last planet in our solar system,
but it wasn't always that way!

For almost 100 years, Neptune was known as the last planet in our solar system.
Then in 1930, someone discovered Pluto!

For 40 years, Pluto was the furthest planet from the Sun in our solar system,
but then in 1979 it's orbit brought it closer to the Sun and Neptune became the furthest (and ninth) planet.

It was like that for 20 years and then switched back to Pluto being furthest.

Then in 2006, Pluto was reclassified as a dwarf planet,
making Neptune the furthest again.
