Think of it like this:
* The head: This is the most recognizable part, with the bright star Menkar marking the whale's jaw.
* The body: Stretches out like a long, winding serpent, with no defined curves or edges.
* The tail: Ends in a faint, less prominent section.
You can find some guides that might try to draw a whale shape, but it's more of an artistic interpretation than a clear visual pattern in the stars.
The best way to appreciate Cetus is to trace its path across the sky and imagine the whale's journey.
