helens planet

It seems you might be referring to "Helen's Planet," but there isn't any widely recognized concept or term by that name in astronomy or popular culture as of my last knowledge update in October 2023. If you meant "Helen of Troy," she is a figure from Greek mythology known for her beauty and the role she played in sparking the Trojan War. Alternatively, "Helen" could refer to a specific person's project, an artwork, or a fictional creation. Could you please provide more context or clarify what you mean by "Helen's Planet"? This will help me give you a more accurate and informative response!
