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-110532","name":"HD 110532","class":"k0_1iii_orange_giant","category":"star","object_type":"K0/1III orange giant","mag":6.41,"mag_band":"V","abs_mag":0.257,"abs_mag_band":"V","distance_ly":554.6876284553113,"distance_method":"parallax","ra_deg":190.86816,"dec_deg":-58.902742,"epoch_ra_deg":191.25521,"epoch_dec_deg":-59.049922,"epoch_moved_arcsec":1.897,"pm_ra_mas_yr":-71.12,"pm_dec_mas_yr":-0.34,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Crux","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-110532","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"12435-5854","companions":[{"measured":2016,"magnitude":11,"components":"AB","discoverer_code":"RST 606","separation_arcsec":2.4,"position_angle_deg":161},{"measured":2024,"magnitude":10.02,"components":"AC","discoverer_code":"HJ 4543","separation_arcsec":38.4,"position_angle_deg":93}],"spectral_type":"K0/1III","color_index_bv":1.092,"luminosity_solar":68.73849195903233,"radial_velocity_km_s":17,"spectral_type_source":"SIMBAD (1975MSS...C01....0H, quality D)","proper_motion_ra_mas_yr":-71.12,"proper_motion_dec_mas_yr":-0.34},"designations":[{"catalog":"HD","designation":"HD 110532"},{"catalog":"HIP","designation":"HIP 62084"},{"catalog":"HR","designation":"HR 4835"}],"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.
