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-96","name":"HIP 96","class":"m0_5v_red_dwarf","category":"star","object_type":"M0.5V red dwarf","mag":10.46,"mag_band":"V","abs_mag":7.73,"abs_mag_band":"V","distance_ly":114.64200982916901,"distance_method":"parallax","ra_deg":0.30495,"dec_deg":13.975088,"epoch_ra_deg":0.648808,"epoch_dec_deg":14.125594,"epoch_moved_arcsec":3.768,"pm_ra_mas_yr":20.59,"pm_dec_mas_yr":139.82,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Pegasus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-96","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"00012+1357","companions":[{"measured":2025,"magnitude":13.1,"components":"Aa,Ab","discoverer_code":"LSC   2","separation_arcsec":0.1,"position_angle_deg":69},{"measured":2021,"magnitude":11.12,"components":"AB","discoverer_code":"WNO  12","separation_arcsec":11.5,"position_angle_deg":204}],"spectral_type":"M0.5V","color_index_bv":1.36,"luminosity_solar":0.07046930689671463,"variable_mag_max":10.382,"variable_mag_min":10.732,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1974ApJS...28....1J, quality C)","proper_motion_ra_mas_yr":20.59,"proper_motion_dec_mas_yr":139.82},"designations":[{"catalog":"HIP","designation":"HIP 96"}],"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.
