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-26016","name":"HIP 26016","class":"b8_blue_white_star","category":"star","object_type":"B8 blue-white star","mag":8.6,"mag_band":"V","abs_mag":6.712,"abs_mag_band":"V","distance_ly":77.80460390432914,"distance_method":"parallax","ra_deg":83.273295,"dec_deg":-1.720991,"epoch_ra_deg":83.61305,"epoch_dec_deg":-1.701631,"epoch_moved_arcsec":0.044,"pm_ra_mas_yr":1.1,"pm_dec_mas_yr":1.23,"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-26016","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"05331-0143","companions":[{"measured":2022,"magnitude":9.24,"components":"CD","discoverer_code":"BU 1049","separation_arcsec":0.6,"position_angle_deg":298}],"spectral_type":"B8","color_index_bv":-0.1,"luminosity_solar":0.1799699516577357,"variable_mag_max":8.24,"variable_mag_min":8.65,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (quality D)","proper_motion_ra_mas_yr":1.1,"proper_motion_dec_mas_yr":1.23},"designations":[{"catalog":"HIP","designation":"HIP 26016"}],"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.
