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-35246","name":"HIP 35246","class":"k5_5vk_orange_dwarf","category":"star","object_type":"K5.5Vk: orange dwarf","mag":10.65,"mag_band":"V","abs_mag":7.688,"abs_mag_band":"V","distance_ly":127.60411659238784,"distance_method":"parallax","ra_deg":109.24662000000001,"dec_deg":-59.122712,"epoch_ra_deg":109.35166,"epoch_dec_deg":-59.169951,"epoch_moved_arcsec":2.829,"pm_ra_mas_yr":-106.01,"pm_dec_mas_yr":-3.86,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Carina","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-35246","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"mass_solar":0.674,"radius_solar":0.678,"spectral_type":"K5.5Vk:","color_index_bv":1.03,"luminosity_solar":0.07324871326650399,"variable_mag_max":10.567,"variable_mag_min":10.727,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (2006AJ....132..161G, quality C)","surface_gravity_log_g":4.62,"surface_temperature_k":4297,"proper_motion_ra_mas_yr":-106.01,"proper_motion_dec_mas_yr":-3.86,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.1429},"designations":[{"catalog":"HIP","designation":"HIP 35246"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
