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-214749","name":"HD 214749","class":"k4_5vk_orange_dwarf","category":"star","object_type":"K4.5Vk orange dwarf","mag":7.83,"mag_band":"V","abs_mag":7.17,"abs_mag_band":"V","distance_ly":44.19451533699645,"distance_method":"parallax","ra_deg":340.18062,"dec_deg":-29.67448,"epoch_ra_deg":340.557607,"epoch_dec_deg":-29.534615,"epoch_moved_arcsec":10.149,"pm_ra_mas_yr":380.21,"pm_dec_mas_yr":-17.42,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Piscis Austrinus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-214749","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"radius_solar":0.716,"spectral_type":"K4.5Vk","uncertainties":{"metallicity_fe_h":[0.041,0.041]},"color_index_bv":1.143,"luminosity_solar":0.11803206356517291,"metallicity_fe_h":0.09,"radial_velocity_km_s":1,"spectral_type_source":"SIMBAD (2006AJ....132..161G, quality C)","surface_gravity_log_g":4.588,"surface_temperature_k":4446,"metallicity_fe_h_source":"Median of 4 spectroscopic determinations in 7 papers, compiled from the literature (PASTEL, Soubiran+ 2016); the error bar is the scatter between them","proper_motion_ra_mas_yr":380.21,"proper_motion_dec_mas_yr":-17.42,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.1806},"designations":[{"catalog":"Gliese","designation":"Gl 868"},{"catalog":"HD","designation":"HD 214749"},{"catalog":"HIP","designation":"HIP 111960"}],"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.
