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-124697","name":"HD 124697","class":"g2iii_yellow_giant","category":"star","object_type":"G2III yellow giant","mag":8.71,"mag_band":"V","abs_mag":4.4,"abs_mag_band":"V","distance_ly":237.37726401500126,"distance_method":"parallax","ra_deg":213.568095,"dec_deg":33.928292,"epoch_ra_deg":213.856736,"epoch_dec_deg":33.802877,"epoch_moved_arcsec":2.952,"pm_ra_mas_yr":-107.46,"pm_dec_mas_yr":26.67,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Boötes","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-124697","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"14143+3356","age_years":4312448000,"companions":[{"measured":2018,"magnitude":10.24,"components":"AB","discoverer_code":"STF1818","separation_arcsec":5.4,"position_angle_deg":330}],"mass_solar":1.067,"radius_solar":1.131,"spectral_type":"G2III","color_index_bv":0.65,"luminosity_solar":1.513561248436207,"radial_velocity_km_s":0,"surface_gravity_log_g":4.314,"surface_temperature_k":5986,"proper_motion_ra_mas_yr":-107.46,"proper_motion_dec_mas_yr":26.67,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4) — low confidence: Gaia's classifier calls the source a binary, which GSP-Phot fitted as one star","bolometric_luminosity_solar":1.4692},"designations":[{"catalog":"HD","designation":"HD 124697"},{"catalog":"HIP","designation":"HIP 69555"}],"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.
