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-65","name":"HIP 65","class":"k4v_orange_dwarf","category":"star","object_type":"K4V orange dwarf","mag":11,"mag_band":"V","abs_mag":7.31,"abs_mag_band":"V","distance_ly":178.42254180443362,"distance_method":"parallax","ra_deg":0.18747,"dec_deg":-54.830524,"epoch_ra_deg":0.530772,"epoch_dec_deg":-54.681609,"epoch_moved_arcsec":5.828,"pm_ra_mas_yr":-205.14,"pm_dec_mas_yr":-75.34,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Phoenix","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-65","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"00007-5450","companions":[{"measured":2016,"magnitude":16.12,"components":"AB","discoverer_code":"KPP2838","separation_arcsec":3.8,"position_angle_deg":322},{"measured":2015,"magnitude":18.6,"components":"AC","discoverer_code":"TOI 129","separation_arcsec":73.6,"position_angle_deg":162}],"radius_solar":0.739,"spectral_type":"K4V","color_index_bv":1.147,"luminosity_solar":0.10375284158180126,"variable_mag_max":10.882,"variable_mag_min":11.092,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (2020A&A...639A..76N, quality D)","surface_gravity_log_g":4.593,"surface_temperature_k":4594,"proper_motion_ra_mas_yr":-205.14,"proper_motion_dec_mas_yr":-75.34,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.2207},"designations":[{"catalog":"Exoplanet host","designation":"HIP 65 A"},{"catalog":"HIP","designation":"HIP 65"}],"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.
