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-115094","name":"HIP 115094","class":"k3v_orange_dwarf","category":"star","object_type":"K3V orange dwarf","mag":10.9,"mag_band":"V","abs_mag":6.854,"abs_mag_band":"V","distance_ly":210.1523388542293,"distance_method":"parallax","ra_deg":349.67960999999997,"dec_deg":-34.940325,"epoch_ra_deg":350.043327,"epoch_dec_deg":-34.793743,"epoch_moved_arcsec":1.626,"pm_ra_mas_yr":-50.4,"pm_dec_mas_yr":-34.26,"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-115094","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"age_years":12941009500,"mass_solar":0.735,"radius_solar":0.724,"spectral_type":"K3V","color_index_bv":0.985,"luminosity_solar":0.15790649727284273,"variable_mag_max":10.847,"variable_mag_min":10.967,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1972AJ.....77..486U, quality C)","surface_gravity_log_g":4.577,"surface_temperature_k":4687,"proper_motion_ra_mas_yr":-50.4,"proper_motion_dec_mas_yr":-34.26,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.2331},"designations":[{"catalog":"HIP","designation":"HIP 115094"}],"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.
