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-tr-182-b","name":"OGLE-TR-182 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":8159.617179528628,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":167.3279228,"dec_deg":-61.0952624,"epoch_ra_deg":167.608965,"epoch_dec_deg":-61.240688,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"OGLE-TR-182","semi_major_axis_km":7629491.405699999,"periapsis_km":null,"mass_kg":1.9170360247216938e+27,"mass_msun":0.000964105,"constellation":"Carina","discovered":"2007","featured":false,"url":"https://spacecatalog.org/object/ogle-tr-182-b","radius_km":80785.01460000001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"OGLE-TR-182","host_v_mag":16.9195,"eccentricity":0,"uncertainties":{"mass_kg":[2.8470518659335062e+26,2.8470518659335062e+26],"radius_km":[5721.1557,17157.089],"distance_ly":[1304.1525841192845,1304.1525841192845],"host_mass_solar":[0.05,0.05],"inclination_deg":[0.3,0.3],"host_radius_solar":[0.06,0.23],"host_temperature_k":[64,64],"semi_major_axis_km":[149597.8707,149597.8707],"orbital_period_days":[0.00001,0.00001]},"host_mass_solar":1.14,"inclination_deg":85.7,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.14,"planets_in_system":1,"discovery_facility":"OGLE","host_temperature_k":5924,"orbital_period_days":3.9791,"transit_midpoint_bjd":2454270.572,"equilibrium_temperature_k":1550},"designations":[{"catalog":"Exoplanet","designation":"OGLE-TR-182 b"},{"catalog":"Host star","designation":"OGLE-TR-182"}],"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.
