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-2088-b","name":"TOI-2088 b","class":"neptune_like_planet","category":"exoplanet","object_type":"Neptune-like planet","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":412.4573552605937,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":261.3748943,"dec_deg":75.8822796,"epoch_ra_deg":261.133271,"epoch_dec_deg":75.85726,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2088","semi_major_axis_km":70610194.97039999,"periapsis_km":null,"mass_kg":2.2097021110828104e+26,"mass_msun":0.000111129,"constellation":"Draco","discovered":"2024","featured":false,"url":"https://spacecatalog.org/object/toi-2088-b","radius_km":23491.29427799,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2088","host_v_mag":11.638,"eccentricity":0,"uncertainties":{"radius_km":[897.5452387380001,1229.561635127],"distance_ly":[1.1676398322259414,1.1741629597802763],"host_mass_solar":[0.0254,0.0223],"host_radius_solar":[0.0239,0.0339],"host_temperature_k":[54,56],"semi_major_axis_km":[1346380.8362999998,1346380.8362999998],"orbital_period_days":[0.00065,0.00065]},"host_mass_solar":0.9027,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.8481,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":5081,"orbital_period_days":124.72997,"transit_midpoint_bjd":2458769.6066,"equilibrium_temperature_k":300.33,"argument_of_periastron_deg":90},"designations":[{"catalog":"Exoplanet","designation":"TOI-2088 b"},{"catalog":"Host star","designation":"TOI-2088"}],"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.
