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-94898","name":"HIP 94898","class":"g6v_yellow_main_sequence_star","category":"star","object_type":"G6V yellow main-sequence star","mag":9.49,"mag_band":"V","abs_mag":5.122,"abs_mag_band":"V","distance_ly":243.76405820345056,"distance_method":"parallax","ra_deg":289.67265,"dec_deg":43.236337,"epoch_ra_deg":289.883367,"epoch_dec_deg":43.283312,"epoch_moved_arcsec":5.29,"pm_ra_mas_yr":-24.68,"pm_dec_mas_yr":-196.78,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Lyra","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-94898","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"19187+4314","companions":[{"measured":2016,"magnitude":16.63,"components":null,"discoverer_code":"KPP3339","separation_arcsec":6.1,"position_angle_deg":48}],"radius_solar":1.076,"spectral_type":"G6V","color_index_bv":0.85,"luminosity_solar":0.7783949326267259,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (2022A&A...664A..78F, quality C)","surface_gravity_log_g":4.381,"surface_temperature_k":5286,"proper_motion_ra_mas_yr":-24.68,"proper_motion_dec_mas_yr":-196.78,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.8196},"designations":[{"catalog":"HIP","designation":"HIP 94898"}],"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.
