How many planets are there in the solar system?

Pluto will always be a planet! I demand the points for this question.

Quite. I got it right 'coz I knew it would be a trick question, but Pluto will always be a planet to us oldsters!

Pluto is a planet...sigh

Scientists still discuss in the last twelve years if Pluto should be reclassified as a planet. A dwarf planet is a type of planet and it's in our solar system so I consider little Pluto as still part of our family.

Player #1032817, Agreed. I grew up with Pluto being a planet and it always will be to me. Which sadly meant I got this question wrong.

Player #162237 Alexandra, dwarf planet is a what?.......a planet. small or large, it's still a planet

Dwarf PLANET.... question asks how many PLANETS

Syr Hal, science doesn't change. scientists opinions do

Player #4383989, then you would have to include 4 other recognised dwarf planets (Ceres, Haumea, Makemake and Eris). excluding Pluto is simpler.

You know it's kinda ironic if you think about it. Pluto was named after the Roman God of the Underworld who was crafted after the Greek God of the Underworld Hades who was essentially banished from Mt. Olympus which was the home of the other gods. The other 8 planets are all named after other gods in Roman mythology. scientists have essentially banished Hades again from being accepted as a planet or "god". Which I find kinda hilarious because if I were living in ancient times and believed in the "gods" I would be "praying" to Hades more than any other. Death is certain and is far more eternal than life. Wouldn't you want to be on good terms with the being that determines your afterlife which is essentially your fate for the rest of eternity.

Also, it could/may/might be nine again : Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects, bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth. (*NOT* Pluto)

Rosie-knees, it figured that the younger generation decided to leave out the "Please".

Rosie-knees, so, Pluto is out? Again?

Player #162237 Alexandra, Yep, I have learn that since elementary time that there are 9 planets in the solar system and that includes Pluto.

An east way to remember: My Very Earnest Mother Just Served Us Nachos.

Pluto was changed back from a moon to a planet

Player #162237 Alexandra, Yes but as we all know it didn't got fit in the new definition of planets. In 2006

Pluto is a planet you'll be telling us next it's not a Disney cartoon dog

Player #4383989, I concur wholeheartedly!

Player #4383989, In the words of Heidi Klum "One day you are in, & the next day you are out!" This applies to more than just fashion.

PLUTO is a planet!

I thought Pluto was a dog?

not everyone agrees Pluto is not a planet

All the problems in this world and they are spending their time debating the status of a stone cold rock some billion miles away...I wonder if they had a wet-bar?

OptimisticFrog17914, First the planets , now the genders...people always want to rewrite science!

JazzLicks, one day it is, the next day it isn't. sounds like other topics today. poppycock

OptimisticFrog17914, Science is always open to change when evidence comes along - that is its power!

Sedona has been classified as a planet, so the answer is 9.

Player #162237 Alexandra, I agree!
