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-38678","name":"14 ζ Lep","class":"a2iv_v_n_white_subgiant","category":"star","object_type":"A2IV-V(n) white subgiant","mag":3.55,"mag_band":"V","abs_mag":1.877,"abs_mag_band":"V","distance_ly":70.47456547152305,"distance_method":"parallax","ra_deg":86.738925,"dec_deg":-14.82195,"epoch_ra_deg":87.043408,"epoch_dec_deg":-14.811559,"epoch_moved_arcsec":0.397,"pm_ra_mas_yr":-14.84,"pm_dec_mas_yr":-1.18,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Lepus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-38678","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"spectral_type":"A2IV-V(n)","color_index_bv":0.104,"luminosity_solar":15.459662193866743,"radial_velocity_km_s":16.3,"spectral_type_source":"SIMBAD (2006AJ....132..161G, quality C)","surface_temperature_k":8776,"proper_motion_ra_mas_yr":-14.84,"proper_motion_dec_mas_yr":-1.18,"stellar_parameters_method":"Spectroscopic determinations compiled from the literature (PASTEL, Soubiran+ 2016)"},"designations":[{"catalog":"Bayer/Flamsteed","designation":"14 Zeta Lep"},{"catalog":"Gliese","designation":"Gl 217.1"},{"catalog":"HD","designation":"HD 38678"},{"catalog":"HIP","designation":"HIP 27288"},{"catalog":"HR","designation":"HR 1998"}],"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.
