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-836-01","name":"TOI-836.01","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":89.70083162516964,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":225.0798831,"dec_deg":-24.4542022,"epoch_ra_deg":225.471842,"epoch_dec_deg":-24.561092,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-836","semi_major_axis_km":11219840.302499998,"periapsis_km":null,"mass_kg":5.733281153079724e+25,"mass_msun":0.0000288335,"constellation":"Libra","discovered":"2021","featured":false,"url":"https://spacecatalog.org/object/toi-836-01","radius_km":16500.1447,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-836","host_v_mag":9.92,"eccentricity":0.078,"uncertainties":{"mass_kg":[1.4930419669478448e+25,1.6124853243036724e+25],"radius_km":[561.2728,561.2728],"distance_ly":[0.09556381867100582,0.09588997504872256],"eccentricity":[0.056,0.056],"host_mass_solar":[0.041,0.049],"inclination_deg":[1.5,1.5],"host_radius_solar":[0.01,0.01],"host_temperature_k":[154,154],"semi_major_axis_km":[239356.59312,239356.59312],"orbital_period_days":[0.00001,0.00001],"argument_of_periastron_deg":[113,113]},"host_mass_solar":0.678,"inclination_deg":88.7,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.665,"planets_in_system":2,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"K V","host_temperature_k":4552,"orbital_period_days":8.59545,"transit_midpoint_bjd":2458599.7623,"equilibrium_temperature_k":665,"argument_of_periastron_deg":-28},"designations":[{"catalog":"Exoplanet","designation":"TOI-836.01"},{"catalog":"Host star","designation":"TOI-836"}],"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.
