The sphere shows an ultra-cool red glow in infrared scans. It appears too dim to be a star. Yet too massive for a typical planet. Its behaviour blurs rigid boundaries of object classification. Existing models struggle to explain how it attained such velocity. Astronomers have yet to agree on a definitive classification.
