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-143314","name":"HD 143314","class":"k4_orange_star","category":"star","object_type":"K4 orange star","mag":8.46,"mag_band":"V","abs_mag":0.824,"abs_mag_band":"V","distance_ly":1098.1695022414083,"distance_method":"parallax","ra_deg":239.7222,"dec_deg":21.791269,"epoch_ra_deg":240.015143,"epoch_dec_deg":21.714422,"epoch_moved_arcsec":0.867,"pm_ra_mas_yr":-14.78,"pm_dec_mas_yr":28.92,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Serpens","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-143314","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"15589+2147","companions":[{"measured":2013,"magnitude":12.43,"components":"AD","discoverer_code":"WAL  69","separation_arcsec":15,"position_angle_deg":262},{"measured":2017,"magnitude":9.25,"components":"AB","discoverer_code":"STF1990","separation_arcsec":56.6,"position_angle_deg":61},{"measured":2017,"magnitude":9.29,"components":"AC","discoverer_code":"STF1990","separation_arcsec":58.5,"position_angle_deg":60}],"spectral_type":"K4","luminosity_solar":40.77556617502125,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (quality C)","proper_motion_ra_mas_yr":-14.78,"proper_motion_dec_mas_yr":28.92},"designations":[{"catalog":"HD","designation":"HD 143314"},{"catalog":"HIP","designation":"HIP 78269"}],"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.
