SELECT astro_angular_separation(10.68, 41.27, 83.82, -5.39) AS separation_deg;
The astro extension adds 62 functions (59 scalar + 3 FITS table functions) to DuckDB: coordinate transforms (equatorial / galactic frames, RA/Dec to XYZ), angular separation, photometry (magnitude/flux, distance modulus, absolute magnitude), CCM89 + O'Donnell 1994 dust extinction with UBVRIJHK bands, cosmological distances (luminosity, comoving), celestial body models (stars, brown dwarfs, planets, black holes, asteroids), Keplerian orbital mechanics, 3D octree spatial sectors, sidereal time / observation planning (GMST, LMST, hour angle, equatorial to horizontal alt/az conversion), and FITS file I/O (fits_hdus, fits_header, read_fits via cfitsio) for reading astronomical catalogs and images directly from SQL.
