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-60779-c","name":"HD 60779 c","class":"neptune_like_planet","category":"exoplanet","object_type":"Neptune-like planet","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":115.60449729981111,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":114.0047579,"dec_deg":-3.151291,"epoch_ra_deg":114.3413,"epoch_dec_deg":-3.21044,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HD 60779","semi_major_axis_km":null,"periapsis_km":null,"mass_kg":1.6901235065849605e+26,"mass_msun":0.0000849987,"constellation":"Monoceros","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/hd-60779-c","radius_km":36929.199,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HD 60779","host_v_mag":7.1634,"eccentricity":0.041,"uncertainties":{"mass_kg":[8.958251801687069e+24,8.958251801687069e+24],"distance_ly":[0.15198887201600245,0.15231502839371916],"eccentricity":[0.029,0.041],"host_mass_solar":[0.044,0.044],"host_radius_solar":[0.013,0.013],"host_temperature_k":[60,60],"orbital_period_days":[0.23,0.23]},"host_mass_solar":1.05,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":1.129,"planets_in_system":2,"discovery_facility":"Roque de los Muchachos Observatory","host_spectral_type":"G1 V","host_temperature_k":6081,"orbital_period_days":104.79,"transit_midpoint_bjd":2459269.5},"designations":[{"catalog":"Exoplanet","designation":"HD 60779 c"}],"source":{"id":"exoplanet_archive","name":"NASA Exoplanet Archive (Planetary Systems Composite Parameters)","url":"https://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=PSCompPars","license":"Public domain (NASA)"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
