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-134060-c","name":"HD 134060 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":78.31830019923301,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":227.6847587,"dec_deg":-61.4223747,"epoch_ra_deg":228.230572,"epoch_dec_deg":-61.524265,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HD 134060","semi_major_axis_km":357957785.0109599,"periapsis_km":null,"mass_kg":1.749247968476095e+26,"mass_msun":0.0000879722,"constellation":"Circinus","discovered":"2019","featured":false,"url":"https://spacecatalog.org/object/hd-134060-c","radius_km":37694.571,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HD 134060","host_v_mag":6.29,"eccentricity":0.11,"uncertainties":{"mass_kg":[2.532199175943545e+25,2.6456703654315807e+25],"distance_ly":[0.06620974467649891,0.06653590105421567],"eccentricity":[0.07,0.13],"host_radius_solar":[0.018391,0.009495],"host_temperature_k":[14,14],"semi_major_axis_km":[14226757.50357,13897642.188029999],"orbital_period_days":[44.2197,48.0333],"argument_of_periastron_deg":[55.51,121.28]},"host_mass_solar":1.095,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":1.164285,"planets_in_system":2,"discovery_facility":"La Silla Observatory","host_spectral_type":"G3 IV","host_temperature_k":5966,"orbital_period_days":1291.5646,"periastron_epoch_bjd":2455232.816,"equilibrium_temperature_k":200.67,"argument_of_periastron_deg":-132.73},"designations":[{"catalog":"Exoplanet","designation":"HD 134060 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.
