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-67767","name":"14 ψ Cnc","class":"g7v_yellow_main_sequence_star","category":"star","object_type":"G7V yellow main-sequence star","mag":5.73,"mag_band":"V","abs_mag":2.647,"abs_mag_band":"V","distance_ly":134.886862350425,"distance_method":"parallax","ra_deg":122.61327,"dec_deg":25.507334,"epoch_ra_deg":123.017229,"epoch_dec_deg":25.42565,"epoch_moved_arcsec":9.48,"pm_ra_mas_yr":-71.82,"pm_dec_mas_yr":-348.06,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Cancer","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-67767","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"08105+2530","age_years":2433093500,"companions":[{"measured":1928,"magnitude":6.6,"components":"Aa,Ab","discoverer_code":"OCC  73","separation_arcsec":0.1,"position_angle_deg":-1},{"measured":2011,"magnitude":13.11,"components":"AB","discoverer_code":"BUP 112","separation_arcsec":88.4,"position_angle_deg":316},{"measured":2001,"magnitude":11.79,"components":"AC","discoverer_code":"BUP 112","separation_arcsec":89.7,"position_angle_deg":219}],"mass_solar":1.56,"radius_solar":3.532,"spectral_type":"G7V","color_index_bv":0.825,"luminosity_solar":7.606765007662268,"radial_velocity_km_s":-43,"spectral_type_source":"SIMBAD (1979PASP...91...83C, quality C)","surface_gravity_log_g":3.337,"surface_temperature_k":5162,"proper_motion_ra_mas_yr":-71.82,"proper_motion_dec_mas_yr":-348.06,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":7.9846},"designations":[{"catalog":"Bayer/Flamsteed","designation":"14 Psi Cnc"},{"catalog":"HD","designation":"HD 67767"},{"catalog":"HIP","designation":"HIP 40023"},{"catalog":"HR","designation":"HR 3191"}],"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.
