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-13174","name":"14 Ari","class":"f2iii_yellow_white_giant","category":"star","object_type":"F2III yellow-white giant","mag":4.98,"mag_band":"V","abs_mag":0.245,"abs_mag_band":"V","distance_ly":288.6340433986984,"distance_method":"parallax","ra_deg":32.355540000000005,"dec_deg":25.939892,"epoch_ra_deg":32.738393,"epoch_dec_deg":26.066867,"epoch_moved_arcsec":2.246,"pm_ra_mas_yr":77.5,"pm_dec_mas_yr":-33.1,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Aries","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-13174","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"02094+2556","companions":[{"measured":2014,"magnitude":8.01,"components":"AB","discoverer_code":"H 6  69","separation_arcsec":93.1,"position_angle_deg":35},{"measured":2023,"magnitude":7.97,"components":"AC","discoverer_code":"H 6  69","separation_arcsec":106.2,"position_angle_deg":279}],"spectral_type":"F2III","uncertainties":{"metallicity_fe_h":[0.39,0.39]},"color_index_bv":0.339,"luminosity_solar":69.50243175887965,"metallicity_fe_h":0.47,"radial_velocity_km_s":1,"spectral_type_source":"SIMBAD (quality C)","surface_gravity_log_g":3.49,"surface_temperature_k":6710,"metallicity_fe_h_source":"One spectroscopic determination, compiled from the literature (PASTEL, Soubiran+ 2016)","proper_motion_ra_mas_yr":77.5,"proper_motion_dec_mas_yr":-33.1,"stellar_parameters_method":"Spectroscopic determinations compiled from the literature (PASTEL, Soubiran+ 2016)"},"designations":[{"catalog":"Bayer/Flamsteed","designation":"14 Ari"},{"catalog":"HD","designation":"HD 13174"},{"catalog":"HIP","designation":"HIP 10053"},{"catalog":"HR","designation":"HR 623"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-27T19:16:43.430Z","attribution":"Data from SpaceCatalog.org.
