The catalogued J2000 position is carried along the great circle the object's own published motion puts it on, at a constant velocity, and the result is referred to the true equator and equinox of this instant. Those are separate things: the motion moves the object, and the rotation turns the grid under it by about fifty arcseconds a year, with nutation adding up to another seventeen.","excluded":"Parallax, the radial-velocity perspective term, aberration and refraction; each is below the accuracy of the catalogued positions themselves. An object with no published proper motion comes back where the catalogue has it rather than at a fabricated zero, and says so with a null pm_ra_mas_yr. A body with no fixed position is not propagated at all — its place comes from an ephemeris, which is what /api/v1/visible answers with."},"slug":"dabih","name":"Dabih","class":"g9ii_b8p_si_yellow_bright_giant","category":"star","object_type":"G9II:+B8p:Si: yellow bright giant","mag":3.05,"mag_band":"V","abs_mag":-1.954,"abs_mag_band":"V","distance_ly":326.80999509768776,"distance_method":"parallax","ra_deg":305.25280499999997,"dec_deg":-14.781367,"epoch_ra_deg":305.629502,"epoch_dec_deg":-14.696489,"epoch_moved_arcsec":1.343,"pm_ra_mas_yr":48.42,"pm_dec_mas_yr":14,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Capricornus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/dabih","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"20210-1447","companions":[{"measured":2000,"magnitude":12.96,"components":"AD","discoverer_code":"HJ 2948","separation_arcsec":115.9,"position_angle_deg":292},{"measured":2016,"magnitude":6.08,"components":"AB","discoverer_code":"STFA 52","separation_arcsec":205.2,"position_angle_deg":266},{"measured":2012,"magnitude":8.83,"components":"AC","discoverer_code":"STFA 52","separation_arcsec":226.1,"position_angle_deg":133}],"spectral_type":"G9II:+B8p:Si:","color_index_bv":0.79,"luminosity_solar":526.744488331906,"radial_velocity_km_s":-19,"spectral_type_source":"SIMBAD (2002ApJS..143..513G, quality D)","proper_motion_ra_mas_yr":48.42,"proper_motion_dec_mas_yr":14},"designations":[{"catalog":"Bayer/Flamsteed","designation":"9 Beta Cap"},{"catalog":"Common name","designation":"Dabih"},{"catalog":"HD","designation":"HD 193495"},{"catalog":"HIP","designation":"HIP 100345"},{"catalog":"HR","designation":"HR 7776"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-27T16:03:54.983Z","attribution":"Data from SpaceCatalog.org.
