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-14026","name":"HD 14026","class":"f5_yellow_white_star","category":"star","object_type":"F5 yellow-white star","mag":8.57,"mag_band":"V","abs_mag":3.379,"abs_mag_band":"V","distance_ly":356.06589602250193,"distance_method":"parallax","ra_deg":34.577085000000004,"dec_deg":57.815809,"epoch_ra_deg":35.054553,"epoch_dec_deg":57.939453,"epoch_moved_arcsec":1.721,"pm_ra_mas_yr":36.87,"pm_dec_mas_yr":-52.94,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Perseus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-14026","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"age_years":3148318300,"mass_solar":1.229,"radius_solar":1.434,"spectral_type":"F5","color_index_bv":0.45,"luminosity_solar":3.876144867002411,"radial_velocity_km_s":-7,"spectral_type_source":"SIMBAD (1978A&AS...32...25R, quality D)","surface_gravity_log_g":4.199,"surface_temperature_k":6310,"proper_motion_ra_mas_yr":36.87,"proper_motion_dec_mas_yr":-52.94,"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":2.9244},"designations":[{"catalog":"HD","designation":"HD 14026"},{"catalog":"HIP","designation":"HIP 10751"}],"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.
