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":"hd-112802","name":"HD 112802","class":"k0_orange_star","category":"star","object_type":"K0 orange star","mag":7.87,"mag_band":"V","abs_mag":0.578,"abs_mag_band":"V","distance_ly":937.2308992208583,"distance_method":"parallax","ra_deg":194.78832,"dec_deg":7.900758,"epoch_ra_deg":195.126824,"epoch_dec_deg":7.755791,"epoch_moved_arcsec":1.681,"pm_ra_mas_yr":-62.97,"pm_dec_mas_yr":3.21,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Virgo","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-112802","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"12592+0754","companions":[{"measured":2015,"magnitude":11.38,"components":null,"discoverer_code":"STF1703","separation_arcsec":8.2,"position_angle_deg":259}],"spectral_type":"K0","color_index_bv":1.08,"luminosity_solar":51.144625159630465,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1993yCat.3135....0C, quality E)","proper_motion_ra_mas_yr":-62.97,"proper_motion_dec_mas_yr":3.21},"designations":[{"catalog":"HD","designation":"HD 112802"},{"catalog":"HIP","designation":"HIP 63376"}],"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.
