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":"g-268-110-b","name":"G 268-110 b","class":"terrestrial_planet","category":"exoplanet","object_type":"Terrestrial planet","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":null,"distance_method":null,"ra_deg":16.223688,"dec_deg":-18.124802,"epoch_ra_deg":16.554958,"epoch_dec_deg":-17.980626,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"G 268-110","semi_major_axis_km":1919340.6810809998,"periapsis_km":null,"mass_kg":9.077695159042896e+24,"mass_msun":0.0000045653,"constellation":"Cetus","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/g-268-110-b","radius_km":7207.253,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"G 268-110","host_v_mag":14.7,"eccentricity":0,"uncertainties":{"mass_kg":[1.4930419669478448e+24,1.4930419669478448e+24],"host_mass_solar":[0.009,0.009],"host_radius_solar":[0.03,0.03],"semi_major_axis_km":[43383.38250299999,41887.40379599999],"orbital_period_days":[0.000076,0.000072]},"host_mass_solar":0.137,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":0.177,"planets_in_system":1,"discovery_facility":"Calar Alto Observatory","host_spectral_type":"M5.0 V","orbital_period_days":1.43263,"transit_midpoint_bjd":2457613.435,"equilibrium_temperature_k":534},"designations":[{"catalog":"Exoplanet","designation":"G 268-110 b"},{"catalog":"Host star","designation":"G 268-110"}],"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.
