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-32274","name":"HD 32274","class":"f7v_yellow_white_main_sequence_star","category":"star","object_type":"F7V yellow-white main-sequence star","mag":8.31,"mag_band":"V","abs_mag":4.359,"abs_mag_band":"V","distance_ly":201.20684788259217,"distance_method":"parallax","ra_deg":75.48816,"dec_deg":1.04966,"epoch_ra_deg":75.835708,"epoch_dec_deg":1.089279,"epoch_moved_arcsec":3.342,"pm_ra_mas_yr":115,"pm_dec_mas_yr":49.77,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Orion","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-32274","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"age_years":5305826000,"mass_solar":1.105,"radius_solar":1.297,"spectral_type":"F7V","color_index_bv":0.571,"luminosity_solar":1.571809828203918,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1999MSS...C05....0H, quality C)","surface_gravity_log_g":4.258,"surface_temperature_k":6027,"proper_motion_ra_mas_yr":115,"proper_motion_dec_mas_yr":49.77,"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":1.99},"designations":[{"catalog":"HD","designation":"HD 32274"},{"catalog":"HIP","designation":"HIP 23414"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
