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":"hd-95190","name":"HD 95190","class":"a2_white_star","category":"star","object_type":"A2 white star","mag":7.24,"mag_band":"V","abs_mag":1.655,"abs_mag_band":"V","distance_ly":426.9064089498231,"distance_method":"parallax","ra_deg":164.88774,"dec_deg":9.930795,"epoch_ra_deg":165.238457,"epoch_dec_deg":9.786923,"epoch_moved_arcsec":1.331,"pm_ra_mas_yr":-49.51,"pm_dec_mas_yr":-6.2,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Leo","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-95190","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"10596+0956","age_years":951637800,"companions":[{"measured":2016,"magnitude":12,"components":"AB","discoverer_code":"A  2774","separation_arcsec":1.9,"position_angle_deg":109}],"mass_solar":1.847,"radius_solar":2.295,"spectral_type":"A2","color_index_bv":0.255,"luminosity_solar":18.967059212111455,"radial_velocity_km_s":-2.8,"spectral_type_source":"SIMBAD (1993yCat.3135....0C, quality E)","surface_gravity_log_g":3.926,"surface_temperature_k":7746,"proper_motion_ra_mas_yr":-49.51,"proper_motion_dec_mas_yr":-6.2,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4) — low confidence: above 7,500 K GSP-Phot's temperature and extinction are degenerate","bolometric_luminosity_solar":16.0876},"designations":[{"catalog":"HD","designation":"HD 95190"},{"catalog":"HIP","designation":"HIP 53727"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
