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-25716","name":"HIP 25716","class":"m0_5v_red_dwarf","category":"star","object_type":"M0.5V red dwarf","mag":10.55,"mag_band":"V","abs_mag":9.365,"abs_mag_band":"V","distance_ly":56.282523007934394,"distance_method":"parallax","ra_deg":82.36258500000001,"dec_deg":15.577293,"epoch_ra_deg":82.747452,"epoch_dec_deg":15.598007,"epoch_moved_arcsec":4.042,"pm_ra_mas_yr":-82.74,"pm_dec_mas_yr":-126.92,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Orion","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-25716","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"05296+1534","companions":[{"measured":2016,"magnitude":13.89,"components":"AB","discoverer_code":"LDS6187","separation_arcsec":14.8,"position_angle_deg":299},{"measured":2016,"magnitude":14.7,"components":"AC","discoverer_code":"FYM 217","separation_arcsec":27.2,"position_angle_deg":335}],"spectral_type":"M0.5V","color_index_bv":1.5,"luminosity_solar":0.01563147642640953,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (2013AJ....145..102L, quality C)","proper_motion_ra_mas_yr":-82.74,"proper_motion_dec_mas_yr":-126.92},"designations":[{"catalog":"Gliese","designation":"GJ 2043A"},{"catalog":"HIP","designation":"HIP 25716"}],"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.
