Class Definition Unrecognized by Compiler

Sh0es (92)
So I'm working on a project and I'm trying to make a simple class which. for some reason, isn't being recognized by the compiler. Any time I declare an object of it in another file I get an "undeclared identifier" error.

My class is as follows:

Does your Star header also include this header? If so, you have a circular dependency - this is how you fix that:

I was thinking that might be the case. I put the Star class in this header, but now it's making a similar complaint about the Star* in this class.
LB (13399)
Did you read that article? It explains how to fix that.
Sh0es (92)
I tried a fix explained in the article, putting a templated/typedefed forward declaration of class "Star" before my "Planet" class declaration. I put my star class in the same file as my planet class, and finally, I put the definition of the planet class in a separate file. All this seems to not have worked. Now I'm getting a "redefinition; different basic types" error at the top of my build log.

The terms "template" and "typedef" should not be anywhere near the term "forward declaration" - what exactly is your current code?
Sh0es (92)
Never mind I've found a way around it. My code works well enough now.

You should modify it to say "thank you"

What for?
S G H (2638)
DO NOT edit this for the "thank you".
You WILL get hate. I hate it myself.

Just mark it as solved, there is a button for that if you really feel like - or just leave it as it is.
If you feel extra nice, point out how you did it, so that this post can become useful for future visitors.
