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-1075-b","name":"TOI-1075 b","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":200.45310049368877,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":309.9712091,"dec_deg":-65.4496994,"epoch_ra_deg":310.56751,"epoch_dec_deg":-65.354866,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1075","semi_major_axis_km":1733839.3214129999,"periapsis_km":null,"mass_kg":5.942307028452422e+25,"mass_msun":0.0000298847,"constellation":"Pavo","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/toi-1075-b","radius_km":11423.1771,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-1075","host_v_mag":12.615,"eccentricity":0,"uncertainties":{"mass_kg":[7.763818228128793e+24,8.122148300196277e+24],"radius_km":[516.6261000000001,739.8596000000001],"distance_ly":[0.3077285423757474,0.3077285423757474],"host_mass_solar":[0.03,0.03],"inclination_deg":[3.93,3.34],"host_radius_solar":[0.024,0.024],"host_temperature_k":[75,75],"semi_major_axis_km":[29919.57414,34407.510260999996],"orbital_period_days":[0.0000032,0.0000032]},"host_mass_solar":0.604,"inclination_deg":84.67,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.581,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"K9 V/M0 V","host_temperature_k":3875,"orbital_period_days":0.6047328,"transit_midpoint_bjd":2458654.251,"equilibrium_temperature_k":1323},"designations":[{"catalog":"Exoplanet","designation":"TOI-1075 b"},{"catalog":"Host star","designation":"TOI-1075"}],"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":"2026-08-27T19:16:43.430Z","attribution":"Data from SpaceCatalog.org.
