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":"hip-114383","name":"HIP 114383","class":"orange_star","category":"star","object_type":"Orange star","mag":10.42,"mag_band":"V","abs_mag":5.427,"abs_mag_band":"V","distance_ly":325.1808439909926,"distance_method":"parallax","ra_deg":347.49168,"dec_deg":-28.720052,"epoch_ra_deg":347.855865,"epoch_dec_deg":-28.573986,"epoch_moved_arcsec":5.371,"pm_ra_mas_yr":186.82,"pm_dec_mas_yr":75.57,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Sculptor","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-114383","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"color_index_bv":0.943,"luminosity_solar":0.5877599636805999,"variable_mag_max":10.376,"variable_mag_min":10.476,"radial_velocity_km_s":0,"proper_motion_ra_mas_yr":186.82,"proper_motion_dec_mas_yr":75.57},"designations":[{"catalog":"HIP","designation":"HIP 114383"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-27T19:16:43.430Z","attribution":"Data from SpaceCatalog.org.
