Jupiter
noun
The tree star is the planet Jupiter. Imagine Jupiter covered in very strange trees — the kind that are able to take root in gas! It's a pretty weird image, but will hopefully help you to remember this word. Alternatively, think about how the clouds around Jupiter make patterns that look a lot like wood grain.
