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-107295","name":"HD 107295","class":"k0iii_f_g_orange_giant","category":"star","object_type":"K0III+F/G orange giant","mag":5.94,"mag_band":"V","abs_mag":0.574,"abs_mag_band":"V","distance_ly":385.98389439408106,"distance_method":"parallax","ra_deg":185.04489,"dec_deg":-22.1757,"epoch_ra_deg":185.392863,"epoch_dec_deg":-22.325062,"epoch_moved_arcsec":2.926,"pm_ra_mas_yr":-105.42,"pm_dec_mas_yr":-30.25,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Corvus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-107295","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"12206-2213","companions":[{"measured":2022,"magnitude":8.05,"components":"CD","discoverer_code":"BU  605","separation_arcsec":0.5,"position_angle_deg":272}],"spectral_type":"K0III+F/G","color_index_bv":0.824,"luminosity_solar":51.33339643802892,"radial_velocity_km_s":-1,"spectral_type_source":"SIMBAD (1988MSS...C04....0H, quality C)","proper_motion_ra_mas_yr":-105.42,"proper_motion_dec_mas_yr":-30.25},"designations":[{"catalog":"HD","designation":"HD 107295"},{"catalog":"HIP","designation":"HIP 60157"},{"catalog":"HR","designation":"HR 4691"}],"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.
