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-70968","name":"HD 70968","class":"k5_orange_star","category":"star","object_type":"K5 orange star","mag":7.84,"mag_band":"V","abs_mag":0.366,"abs_mag_band":"V","distance_ly":1019.2386803648232,"distance_method":"parallax","ra_deg":126.744795,"dec_deg":49.565303,"epoch_ra_deg":127.230257,"epoch_dec_deg":49.476935,"epoch_moved_arcsec":0.997,"pm_ra_mas_yr":-8.7,"pm_dec_mas_yr":-36.37,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Lynx","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-70968","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"spectral_type":"K5","color_index_bv":1.587,"luminosity_solar":62.172738929396054,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1993yCat.3135....0C, quality E)","proper_motion_ra_mas_yr":-8.7,"proper_motion_dec_mas_yr":-36.37},"designations":[{"catalog":"HD","designation":"HD 70968"},{"catalog":"HIP","designation":"HIP 41427"}],"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.
