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-68700","name":"HIP 68700","class":"k0_orange_star","category":"star","object_type":"K0 orange star","mag":9.51,"mag_band":"V","abs_mag":3.595,"abs_mag_band":"V","distance_ly":497.18952062762645,"distance_method":"parallax","ra_deg":210.94152,"dec_deg":42.304361,"epoch_ra_deg":211.217027,"epoch_dec_deg":42.175287,"epoch_moved_arcsec":0.898,"pm_ra_mas_yr":-27.05,"pm_dec_mas_yr":20.07,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Canes Venatici","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-68700","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"spectral_type":"K0","color_index_bv":0.823,"luminosity_solar":3.1768740706497707,"variable_mag_max":9.457,"variable_mag_min":9.567,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (quality D)","proper_motion_ra_mas_yr":-27.05,"proper_motion_dec_mas_yr":20.07},"designations":[{"catalog":"HIP","designation":"HIP 68700"}],"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.
