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-27292","name":"HD 27292","class":"k2_iii_orange_star","category":"star","object_type":"K2+III orange star","mag":7.13,"mag_band":"V","abs_mag":-0.317,"abs_mag_band":"V","distance_ly":1006.6555673125112,"distance_method":"parallax","ra_deg":65.239605,"dec_deg":50.25483,"epoch_ra_deg":65.746321,"epoch_dec_deg":50.318907,"epoch_moved_arcsec":0.081,"pm_ra_mas_yr":-0.04,"pm_dec_mas_yr":-3.04,"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-27292","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"04210+5015","companions":[{"measured":2015,"magnitude":14.8,"components":"AD","discoverer_code":"ES 2604","separation_arcsec":24.8,"position_angle_deg":321},{"measured":2017,"magnitude":8.19,"components":"AB","discoverer_code":"S   445","separation_arcsec":71,"position_angle_deg":328},{"measured":2016,"magnitude":9.3,"components":"AC","discoverer_code":"S   445","separation_arcsec":150.3,"position_angle_deg":263}],"mass_solar":7.2,"radius_solar":96.248,"spectral_type":"K2+III","color_index_bv":1.69,"luminosity_solar":116.62724050819654,"radial_velocity_km_s":-12.7,"spectral_type_source":"SIMBAD (1989ApJS...71..245K, quality C)","surface_gravity_log_g":1.261,"surface_temperature_k":4361,"proper_motion_ra_mas_yr":-0.04,"proper_motion_dec_mas_yr":-3.04,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":2421.369},"designations":[{"catalog":"HD","designation":"HD 27292"},{"catalog":"HIP","designation":"HIP 20296"}],"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.
