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-69072","name":"HD 69072","class":"k0_orange_star","category":"star","object_type":"K0 orange star","mag":7.54,"mag_band":"V","abs_mag":1.21,"abs_mag_band":"V","distance_ly":601.7643877021906,"distance_method":"parallax","ra_deg":123.99351000000001,"dec_deg":18.693896,"epoch_ra_deg":124.379526,"epoch_dec_deg":18.611726,"epoch_moved_arcsec":0.604,"pm_ra_mas_yr":-17.14,"pm_dec_mas_yr":-14.78,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Cancer","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-69072","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"08160+1842","age_years":376751480,"companions":[{"measured":2012,"magnitude":7.5,"components":"Aa,Ab","discoverer_code":"JCT   3","separation_arcsec":0.1,"position_angle_deg":26},{"measured":2016,"magnitude":10.51,"components":"AB","discoverer_code":"HO  524","separation_arcsec":4.4,"position_angle_deg":346},{"measured":2017,"magnitude":9.78,"components":"AC","discoverer_code":"OPI  13","separation_arcsec":66.5,"position_angle_deg":78}],"mass_solar":3.002,"radius_solar":10.755,"spectral_type":"K0","color_index_bv":1.057,"luminosity_solar":28.575905433749465,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1993yCat.3135....0C, quality E)","surface_gravity_log_g":2.581,"surface_temperature_k":4819,"proper_motion_ra_mas_yr":-17.14,"proper_motion_dec_mas_yr":-14.78,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":59.1821},"designations":[{"catalog":"HD","designation":"HD 69072"},{"catalog":"HIP","designation":"HIP 40483"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
