Another issue idea on planets

I have thought of another issue idea which is quite personal to me as I enjoy learning about planets, so my new idea which I have thought of is to do with planets, but I need to come up with some ideas within this issue.

I am going to email my mentor about this and I will hopefully have a mind map with a few ideas on it after he has replied to me. I think that if I have an idea around this issue then it will be a really good final piece which I will produce by the end of it.
