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":"ogle-2023-blg-0836l-b","name":"OGLE-2023-BLG-0836L b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":16699.206539097264,"distance_method":"NASA Exoplanet Archive sy_dist (Han+ 2024, 2024A&A...685A..16H)","ra_deg":267.186875,"dec_deg":-23.7415194,"epoch_ra_deg":267.596863,"epoch_dec_deg":-23.750636,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"OGLE-2023-BLG-0836L","semi_major_axis_km":553512121.59,"periapsis_km":null,"mass_kg":8.275823254939302e+27,"mass_msun":0.00416203,"constellation":"Sagittarius","discovered":"2024","featured":false,"url":"https://spacecatalog.org/object/ogle-2023-blg-0836l-b","radius_km":82277.49,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"OGLE-2023-BLG-0836L","uncertainties":{"mass_kg":[4.137911627469651e+27,4.4605928094282936e+27],"distance_ly":[5251.117681239569,4435.72673694771],"host_mass_solar":[0.36,0.38],"semi_major_axis_km":[173533530.01199996,146605913.28599998]},"host_mass_solar":0.71,"stars_in_system":2,"discovery_method":"Microlensing","planets_in_system":1,"discovery_facility":"OGLE"},"designations":[{"catalog":"Exoplanet","designation":"OGLE-2023-BLG-0836L b"},{"catalog":"Host star","designation":"OGLE-2023-BLG-0836L"}],"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.
