Hi everyone,

I am trying to write a sentence involving the words 'solar system', as in the phrase 'the planets in the solar system' and I am not sure whether it should be capitalized or not.

On the internet there seems to be much disagreement over whether solar system counts as a proper noun or not, and therefore should be capitalized. Does anyone know?

Thanks for your help.

Hi
In my dictionary 'solar system' is not capitalized.
Please refer to your dictionary for more info

You can and you can't.. Following English rules you must not capitalize but if you do that it is still not wrong.
