The article discusses the discovery or study of a celestial object with an unusual orbit far above or below the plane of Earth's orbit, highlighting areas of the solar system that remain under-explored.

Why it matters: Exploring non-Earth-plane orbits opens vast new regions in our solar system for discovery and study.

The big picture: Many orbital resonances and three-body problem solutions remain unknown, offering rich opportunities for astronomy.

The other side: Some question labeling such objects as "rare," since any single object is inherently unique in astronomy.

Commenters say: Readers express surprise about how much space outside Earth's orbital plane remains unexplored and see potential for many new findings.
