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-2092-b","name":"TOI-2092 b","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":576.5107516883385,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":212.5474866,"dec_deg":45.5638685,"epoch_ra_deg":212.811503,"epoch_dec_deg":45.436736,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2092","semi_major_axis_km":null,"periapsis_km":null,"mass_kg":5.374951081012241e+25,"mass_msun":0.0000270314,"constellation":"Boötes","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/toi-2092-b","radius_km":18808.567945541003,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2092","host_v_mag":11.295,"uncertainties":{"radius_km":[1663.000090257,2013.982404806],"distance_ly":[3.268086904721769,3.3072256700477785],"host_mass_solar":[0.116734,0.128799],"inclination_deg":[3.18551,2.02575],"orbital_period_days":[0.00002422764,0.00002596426]},"host_mass_solar":0.956,"inclination_deg":87.00941,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.0519,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":5842.06,"orbital_period_days":4.30325528074,"transit_midpoint_bjd":2459648.65533738,"equilibrium_temperature_k":1042},"designations":[{"catalog":"Exoplanet","designation":"TOI-2092 b"},{"catalog":"Host star","designation":"TOI-2092"}],"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.
