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":"toi-1107-b","name":"TOI-1107 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":917.5235524100797,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":155.6078632,"dec_deg":-82.2188693,"epoch_ra_deg":155.479315,"epoch_dec_deg":-82.354089,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1107","semi_major_axis_km":8392440.54627,"periapsis_km":null,"mass_kg":6.358717409185015e+27,"mass_msun":0.00319789,"constellation":"Chamaeleon","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/toi-1107-b","radius_km":92939.59974347102,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-1107","host_v_mag":10.553,"eccentricity":0.025,"uncertainties":{"mass_kg":[3.4166242795620975e+26,3.4166242795620975e+26],"radius_km":[3574.5999582430004,3574.5999582430004],"distance_ly":[6.532912245666371,6.624236031427059],"eccentricity":[0.016,0.023],"host_mass_solar":[0.08,0.08],"inclination_deg":[0.96,0.89],"host_radius_solar":[0.06,0.06],"host_temperature_k":[98,98],"semi_major_axis_km":[373994.67675,359034.88967999996],"orbital_period_days":[0.0000025,0.0000024],"argument_of_periastron_deg":[42.43,20.48]},"host_mass_solar":1.35,"inclination_deg":88.63,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.81,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"F6 V","host_temperature_k":6311,"orbital_period_days":4.0782387,"transit_midpoint_bjd":2459385.0123,"equilibrium_temperature_k":1728,"argument_of_periastron_deg":71.97},"designations":[{"catalog":"Exoplanet","designation":"TOI-1107 b"},{"catalog":"Host star","designation":"TOI-1107"}],"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.
