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-111482","name":"ι Oct","class":"k0iii_orange_giant","category":"star","object_type":"K0III orange giant","mag":5.45,"mag_band":"V","abs_mag":0.285,"abs_mag_band":"V","distance_ly":351.84086630555925,"distance_method":"parallax","ra_deg":193.743285,"dec_deg":-85.123369,"epoch_ra_deg":194.501086,"epoch_dec_deg":-85.26877,"epoch_moved_arcsec":1.894,"pm_ra_mas_yr":67.47,"pm_dec_mas_yr":22.11,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Octans","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-111482","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"12550-8507","companions":[{"measured":2019,"magnitude":6.86,"components":"AB","discoverer_code":"RST2819","separation_arcsec":0.7,"position_angle_deg":240},{"measured":2015,"magnitude":10,"components":"AC","discoverer_code":"B  9020","separation_arcsec":60.1,"position_angle_deg":53}],"spectral_type":"K0III","color_index_bv":0.991,"luminosity_solar":66.98846094165262,"radial_velocity_km_s":53,"spectral_type_source":"SIMBAD (1975MSS...C01....0H, quality C)","proper_motion_ra_mas_yr":67.47,"proper_motion_dec_mas_yr":22.11},"designations":[{"catalog":"Bayer/Flamsteed","designation":"Iota Oct"},{"catalog":"HD","designation":"HD 111482"},{"catalog":"HIP","designation":"HIP 63031"},{"catalog":"HR","designation":"HR 4870"}],"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.
