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-5624-e","name":"TOI-5624 e","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":332.3957492224647,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":180.8443476,"dec_deg":49.2512257,"epoch_ra_deg":181.18795,"epoch_dec_deg":49.101741,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-5624","semi_major_axis_km":21527133.59373,"periapsis_km":null,"mass_kg":5.315229402334327e+25,"mass_msun":0.0000267311,"constellation":"Ursa Major","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/toi-5624-e","radius_km":20709.6907,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-5624","host_v_mag":10.81,"eccentricity":0,"uncertainties":{"mass_kg":[1.7916503603374138e+25,1.7319286816595e+25],"radius_km":[274.2583,267.88020000000006],"distance_ly":[1.1382857582314345,1.1448088857857692],"host_mass_solar":[0.029,0.033],"inclination_deg":[0.047,0.049],"host_radius_solar":[0.005,0.005],"host_temperature_k":[64,64],"semi_major_axis_km":[224396.80604999998,209437.01898],"orbital_period_days":[0.000029,0.000029]},"host_mass_solar":0.858,"inclination_deg":89.405,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.82,"planets_in_system":5,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":5327,"orbital_period_days":21.489936,"transit_midpoint_bjd":2459655.6215,"equilibrium_temperature_k":613.8,"argument_of_periastron_deg":90},"designations":[{"catalog":"Exoplanet","designation":"TOI-5624 e"},{"catalog":"Host star","designation":"TOI-5624"}],"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":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
