However there is only one star in our solar system - the sun.

Our solar system being the sun and the planets etc that orbit it.

No, the solar system is just the 8 planets that orbit the Sun, so - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. Then there's billions of other stars outside of this.

I was about to correct you and say 9 planets but they fired Pluto, he's now just a dwarf star

When I was a kid Pluto was a real planet

[Stacey.]

I thought Pluto still was a planet?

Nope Pluto is a dwarf planet not a dwarf star, otherwise we would have a two star solar system

We all make mistakes, as the dalek said dismounting from a dustbin.(even questionmeisters -see above).

I wasn't happy when they demoted Pluto, who suddenly makes that decision after all these decades and centuries.

and you can't say "my very easy method just speeds up naming planets" anymore and they've invented a new thing called a "dwarf planet" which Pluto now is along with 3 or 4 others

In the late 20th and early 21st century, many objects similar to Pluto were discovered in the outer Solar System, minor planet Chiron in 1976 disc object Eris in 2005, which is a lot larger than Pluto.

In 2006, the International Astronomical Union (IAU) defined what it means to be a "planet" within the Solar System. This definition excluded Pluto as a planet and added it as a member of the new category "dwarf planet" along with Eris Chiron and Ceres.

After the reclassification, Pluto was added to the list of minor planets and given the number 134340

Saying that there are some groups of astronomers, physicists etc who still regard Pluto as a major planet.
