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-892-b","name":"TOI-892 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1110.7027133679296,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":86.738228,"dec_deg":-11.2353401,"epoch_ra_deg":87.052842,"epoch_dec_deg":-11.224944,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-892","semi_major_axis_km":13763004.104399998,"periapsis_km":null,"mass_kg":1.8032274077491273e+27,"mass_msun":0.000906869,"constellation":"Lepus","discovered":"2020","featured":false,"url":"https://spacecatalog.org/object/toi-892-b","radius_km":76496.571503,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-892","host_v_mag":11.43,"uncertainties":{"mass_kg":[1.328693879394094e+26,1.328693879394094e+26],"radius_km":[1429.842458,1429.842458],"distance_ly":[15.525043579316986,15.962093125457423],"host_mass_solar":[0.02,0.03],"inclination_deg":[0.5,0.3],"host_radius_solar":[0.02,0.02],"host_temperature_k":[80,80],"semi_major_axis_km":[747989.3535,747989.3535],"orbital_period_days":[0.00007,0.00007]},"host_mass_solar":1.28,"inclination_deg":88.2,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.39,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"F","host_temperature_k":6261,"orbital_period_days":10.62656,"transit_midpoint_bjd":2458475.689,"eccentricity_upper_limit":0.125,"equilibrium_temperature_k":1397},"designations":[{"catalog":"Exoplanet","designation":"TOI-892 b"},{"catalog":"Host star","designation":"TOI-892"}],"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.
