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":"hip-112379","name":"HIP 112379","class":"k6v_orange_dwarf","category":"star","object_type":"K6V orange dwarf","mag":10.46,"mag_band":"V","abs_mag":7.3,"abs_mag_band":"V","distance_ly":139.8013866498609,"distance_method":"parallax","ra_deg":341.41571999999996,"dec_deg":45.389872,"epoch_ra_deg":341.713221,"epoch_dec_deg":45.531612,"epoch_moved_arcsec":9.084,"pm_ra_mas_yr":332.22,"pm_dec_mas_yr":74.17,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Lacerta","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-112379","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"22456+4524","companions":[{"measured":2021,"magnitude":11.49,"components":"Aa,Ab","discoverer_code":"HDS3231","separation_arcsec":1,"position_angle_deg":336},{"measured":2021,"magnitude":11.49,"components":"AB","discoverer_code":"LDS4995","separation_arcsec":5.2,"position_angle_deg":10}],"spectral_type":"K6V","color_index_bv":1.24,"luminosity_solar":0.10471285480508993,"variable_mag_max":10.369,"variable_mag_min":10.539,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1947ApJ...105...96J, quality C)","proper_motion_ra_mas_yr":332.22,"proper_motion_dec_mas_yr":74.17},"designations":[{"catalog":"HIP","designation":"HIP 112379"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
