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-65345","name":"14 CMi","class":"g8iiib_yellow_giant","category":"star","object_type":"G8IIIb yellow giant","mag":5.3,"mag_band":"V","abs_mag":0.952,"abs_mag_band":"V","distance_ly":241.59740138627825,"distance_method":"parallax","ra_deg":119.58606,"dec_deg":2.224767,"epoch_ra_deg":119.933908,"epoch_dec_deg":2.153295,"epoch_moved_arcsec":5.08,"pm_ra_mas_yr":-162.54,"pm_dec_mas_yr":99.28,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Canis Minor","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-65345","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"07583+0213","age_years":502552870,"companions":[{"measured":2015,"magnitude":9.36,"components":"AB","discoverer_code":"SHJ  87","separation_arcsec":100.1,"position_angle_deg":84},{"measured":2015,"magnitude":11,"components":"AD","discoverer_code":"SHJ  87","separation_arcsec":101.3,"position_angle_deg":281},{"measured":2017,"magnitude":9.89,"components":"AC","discoverer_code":"SHJ  87","separation_arcsec":134.9,"position_angle_deg":147}],"mass_solar":2.701,"radius_solar":9.43,"spectral_type":"G8IIIb","uncertainties":{"metallicity_fe_h":[0.039,0.039]},"color_index_bv":0.933,"luminosity_solar":36.240985589974414,"metallicity_fe_h":0.01,"radial_velocity_km_s":46,"spectral_type_source":"SIMBAD (1989ApJS...71..245K, quality C)","surface_gravity_log_g":2.759,"surface_temperature_k":5044,"metallicity_fe_h_source":"Median of 8 spectroscopic determinations in 9 papers, compiled from the literature (PASTEL, Soubiran+ 2016); the error bar is the scatter between them","proper_motion_ra_mas_yr":-162.54,"proper_motion_dec_mas_yr":99.28,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":50.3359},"designations":[{"catalog":"Bayer/Flamsteed","designation":"14 CMi"},{"catalog":"HD","designation":"HD 65345"},{"catalog":"HIP","designation":"HIP 38962"},{"catalog":"HR","designation":"HR 3110"}],"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.
