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-61024","name":"HD 61024","class":"k2iii_orange_giant","category":"star","object_type":"K2III orange giant","mag":7.62,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":null,"distance_method":null,"ra_deg":114.061965,"dec_deg":-23.838371,"epoch_ra_deg":114.345213,"epoch_dec_deg":-23.897523,"epoch_moved_arcsec":0.188,"pm_ra_mas_yr":-5.09,"pm_dec_mas_yr":4.87,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Puppis","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-61024","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"07362-2350","companions":[{"measured":2016,"magnitude":9.99,"components":"AB","discoverer_code":"HDO 107","separation_arcsec":20.3,"position_angle_deg":156},{"measured":2015,"magnitude":10.3,"components":"AC","discoverer_code":"HDO 107","separation_arcsec":49.9,"position_angle_deg":337},{"measured":2015,"magnitude":13.66,"components":"AD","discoverer_code":"ABH  69","separation_arcsec":62.4,"position_angle_deg":112}],"mass_solar":7.6,"radius_solar":83.488,"spectral_type":"K2III","color_index_bv":1.227,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1988MSS...C04....0H, quality C)","surface_gravity_log_g":1.362,"surface_temperature_k":4392,"proper_motion_ra_mas_yr":-5.09,"proper_motion_dec_mas_yr":4.87,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":2626.2544},"designations":[{"catalog":"HD","designation":"HD 61024"},{"catalog":"HIP","designation":"HIP 36995"}],"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.
