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-62359","name":"HIP 62359","class":"g0_yellow_star","category":"star","object_type":"G0 yellow star","mag":11.47,"mag_band":"V","abs_mag":5.418,"abs_mag_band":"V","distance_ly":529.4747619886738,"distance_method":"parallax","ra_deg":191.68029,"dec_deg":-62.57977,"epoch_ra_deg":192.077373,"epoch_dec_deg":-62.727789,"epoch_moved_arcsec":5.716,"pm_ra_mas_yr":-129.57,"pm_dec_mas_yr":-170.72,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Crux","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-62359","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"age_years":500974800,"mass_solar":1.017,"radius_solar":0.895,"spectral_type":"G0","color_index_bv":0.63,"luminosity_solar":0.5926523352402152,"variable_mag_max":11.318,"variable_mag_min":11.568,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1995A&AS..110..367N, quality E)","surface_gravity_log_g":4.447,"surface_temperature_k":5758,"proper_motion_ra_mas_yr":-129.57,"proper_motion_dec_mas_yr":-170.72,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.7983},"designations":[{"catalog":"HIP","designation":"HIP 62359"}],"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.
