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-110067-e","name":"HD 110067 e","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":104.88699872803892,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":189.8392243,"dec_deg":20.0273377,"epoch_ra_deg":190.174595,"epoch_dec_deg":19.879753,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HD 110067","semi_major_axis_km":26703219.919949997,"periapsis_km":null,"mass_kg":2.3291454684386377e+25,"mass_msun":0.0000117136,"constellation":"Coma Berenices","discovered":"2023","featured":false,"url":"https://spacecatalog.org/object/hd-110067-e","radius_km":12373.514000000001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HD 110067","host_v_mag":8.419,"uncertainties":{"radius_km":[255.12400000000002,255.12400000000002],"distance_ly":[0.185582978920827,0.18656144805397723],"host_mass_solar":[0.042,0.042],"inclination_deg":[0.089,0.089],"host_radius_solar":[0.008,0.008],"host_temperature_k":[64,64],"semi_major_axis_km":[329115.31554,329115.31554],"orbital_period_days":[0.000012,0.000012]},"host_mass_solar":0.798,"inclination_deg":89.867,"stars_in_system":3,"discovery_method":"Transit","host_radius_solar":0.788,"planets_in_system":6,"discovery_facility":"Multiple Observatories","host_spectral_type":"K0.0 V","host_temperature_k":5266,"orbital_period_days":30.793091,"transit_midpoint_bjd":2459646.0919,"equilibrium_temperature_k":533},"designations":[{"catalog":"Exoplanet","designation":"HD 110067 e"}],"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":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
