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-113414","name":"HD 113414","class":"f7_8v_yellow_white_main_sequence_star","category":"star","object_type":"F7/8V yellow-white main-sequence star","mag":7.74,"mag_band":"V","abs_mag":3.979,"abs_mag_band":"V","distance_ly":184.3732649158756,"distance_method":"parallax","ra_deg":195.912555,"dec_deg":-16.336576,"epoch_ra_deg":196.267571,"epoch_dec_deg":-16.481182,"epoch_moved_arcsec":3.013,"pm_ra_mas_yr":-108.8,"pm_dec_mas_yr":-30.17,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Virgo","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-113414","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"13037-1620","age_years":4883796000,"companions":[{"measured":2020,"magnitude":18.1,"components":null,"discoverer_code":"BNV   8","separation_arcsec":0.6,"position_angle_deg":330}],"mass_solar":1.102,"radius_solar":1.259,"spectral_type":"F7/8V","color_index_bv":0.573,"luminosity_solar":2.2304885593776094,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1988MSS...C04....0H, quality D)","surface_gravity_log_g":4.238,"surface_temperature_k":6064,"proper_motion_ra_mas_yr":-108.8,"proper_motion_dec_mas_yr":-30.17,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":1.9132},"designations":[{"catalog":"HD","designation":"HD 113414"},{"catalog":"HIP","designation":"HIP 63734"}],"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.
