### Polar Regions
|
||||
|
||||
Near the celestial poles (Dec approaching +/-90 degrees), RA becomes degenerate — a small patch of sky spans a wide RA range. Bounding boxes for polar objects may cover the full RA circle. This does not affect **correctness** (the Vincenty formula handles pole convergence naturally) but can degrade **index selectivity** for dense polar catalogs. For typical sky catalogs (fewer than 10,000 objects), the effect is negligible.
