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-68367","name":"HD 68367","class":"g8_k0iv_v_yellow_subgiant","category":"star","object_type":"G8/K0IV/V yellow subgiant","mag":9.88,"mag_band":"V","abs_mag":1.913,"abs_mag_band":"V","distance_ly":1279.0447400062717,"distance_method":"parallax","ra_deg":122.59911,"dec_deg":-41.021096,"epoch_ra_deg":122.832371,"epoch_dec_deg":-41.099937,"epoch_moved_arcsec":0.396,"pm_ra_mas_yr":-14.51,"pm_dec_mas_yr":3.16,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Puppis","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-68367","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"age_years":455442580,"mass_solar":2.794,"radius_solar":10.693,"spectral_type":"G8/K0IV/V","color_index_bv":0.985,"luminosity_solar":14.95546772744395,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1978MSS...C02....0H, quality E)","surface_gravity_log_g":2.804,"surface_temperature_k":5236,"proper_motion_ra_mas_yr":-14.51,"proper_motion_dec_mas_yr":3.16,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":72.4744},"designations":[{"catalog":"HD","designation":"HD 68367"},{"catalog":"HIP","designation":"HIP 40020"}],"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.
