Sister in law wants advice on a name.

My sister in law’s last name is Starr and if she has a boy (she’s not pregnant yet) she wants to name him Polaris. We were talking about names and I think that’s an adorable and fitting name. The middle name however is where I can’t agree. She wants it to be Halonova. So his name would literally be “the North Star and a circular star Starr. It’s just too much “star” you know? I told her the middle name needs work and her husband agreed but she won’t budge. So tell me what you think about that name and I’ll show her your responses. Maybe then the kid will have a semi normal middle name. Maybe it’s not a terrible name after all and I’m just picky.
