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-622-b","name":"TOI-622 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":402.14102903341313,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":125.3050544,"dec_deg":-46.4842959,"epoch_ra_deg":125.519337,"epoch_dec_deg":-46.569095,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-622","semi_major_axis_km":10591529.24556,"periapsis_km":null,"mass_kg":5.751317537203142e+26,"mass_msun":0.000289242,"constellation":"Vela","discovered":"2023","featured":false,"url":"https://spacecatalog.org/object/toi-622-b","radius_km":58909.40785781,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-622","host_v_mag":8.995,"uncertainties":{"mass_kg":[1.3666497115859523e+26,1.3097059736529723e+26],"radius_km":[2073.2679923640003,2001.7759970260004],"distance_ly":[1.5231502839371918,1.5361965390458614],"host_mass_solar":[0.079,0.079],"inclination_deg":[0.54,0.77],"host_radius_solar":[0.047,0.047],"host_temperature_k":[100,100],"semi_major_axis_km":[882627.4371299999,777908.9276399999],"orbital_period_days":[0.000054,0.000031]},"host_mass_solar":1.313,"inclination_deg":86.62,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.415,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"F6 V","host_temperature_k":6400,"orbital_period_days":6.402513,"transit_midpoint_bjd":2458520.69176,"eccentricity_upper_limit":0.42,"equilibrium_temperature_k":1388},"designations":[{"catalog":"Exoplanet","designation":"TOI-622 b"},{"catalog":"Host star","designation":"TOI-622"}],"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.
