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-24554","name":"32 Eri","class":"g8iii_a1v_yellow_giant","category":"star","object_type":"G8III+A1V yellow giant","mag":4.46,"mag_band":"V","abs_mag":-0.451,"abs_mag_band":"V","distance_ly":313.00999260011463,"distance_method":"parallax","ra_deg":58.57293,"dec_deg":-2.95473,"epoch_ra_deg":58.910686,"epoch_dec_deg":-2.875187,"epoch_moved_arcsec":0.706,"pm_ra_mas_yr":26.42,"pm_dec_mas_yr":1.49,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Eridanus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-24554","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"03543-0257","companions":[{"measured":2021,"magnitude":5.89,"components":"AB","discoverer_code":"STF 470","separation_arcsec":6.9,"position_angle_deg":349},{"measured":2017,"magnitude":10.5,"components":"AC","discoverer_code":"STF 470","separation_arcsec":164.7,"position_angle_deg":5}],"spectral_type":"G8III+A1V","color_index_bv":0.672,"luminosity_solar":131.94714571951167,"radial_velocity_km_s":18,"spectral_type_source":"SIMBAD (2008ApJS..176..216A, quality C)","proper_motion_ra_mas_yr":26.42,"proper_motion_dec_mas_yr":1.49},"designations":[{"catalog":"Bayer/Flamsteed","designation":"32 Eri"},{"catalog":"HD","designation":"HD 24554"},{"catalog":"HIP","designation":"HIP 18255"},{"catalog":"HR","designation":"HR 1211"}],"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.
