Pluto is the only "planet" that isn't a planet. Well I think that the IAU still have not answered the question WHAT MAKES A PLANET A PLANET? Is it a certain size or something?

Comment : The IAU have defined a planet. The definition is mainly about size, but it's not simple:

1) The object must be big enough for gravity to have formed it into a (roughly) spherical shape.

2) The object must be by far the largest object in the neighbourhood of its orbit.

Pluto qualifies on 1) but fails on 2).

Also, Venus and Mercury are sometimes called "morning stars" or "evening stars", but they are planets.

The inner planets, Mercury, Venus, Earth and Mars, are "terrestrial" or rocky planets. The outer planets Jupiter, Saturn, Uranus and Neptune are "gas giant" planets, sometimes called "Jovian". The term comes from an alternative term for the Roman god Jupiter, who was sometimes known as "Jove".

The Earth is not a Jovian planet. The 4 outer planets, also known as gas giants, are called Jovian planets and they are Jupiter, Saturn, Uranus and Neptune. By the way, Jovian is the adjective form of the name Jupiter.
