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-715-b","name":"TOI-715 b","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":138.30595965802962,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":113.8523276,"dec_deg":-73.5774089,"epoch_ra_deg":113.728176,"epoch_dec_deg":-73.635641,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-715","semi_major_axis_km":12416623.268099999,"periapsis_km":null,"mass_kg":1.8035946960729965e+25,"mass_msun":0.00000907054,"constellation":"Volans","discovered":"2023","featured":false,"url":"https://spacecatalog.org/object/toi-715-b","radius_km":9886.055,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-715","host_v_mag":16.683,"uncertainties":{"radius_km":[408.19840000000005,408.19840000000005],"distance_ly":[0.2785375465700989,0.2795160157032491],"host_mass_solar":[0.012,0.012],"inclination_deg":[0.017,0.018],"host_radius_solar":[0.012,0.012],"host_temperature_k":[75,75],"semi_major_axis_km":[403914.25088999997,403914.25088999997],"orbital_period_days":[0.000024,0.000027]},"host_mass_solar":0.225,"inclination_deg":89.856,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.24,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"M4","host_temperature_k":3075,"orbital_period_days":19.288004,"transit_midpoint_bjd":2459002.63051,"equilibrium_temperature_k":234},"designations":[{"catalog":"Exoplanet","designation":"TOI-715 b"},{"catalog":"Host star","designation":"TOI-715"}],"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.
