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-6041-b","name":"TOI-6041 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":236.37563777903318,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":46.0610334,"dec_deg":43.5576668,"epoch_ra_deg":46.506821,"epoch_dec_deg":43.662732,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-6041","semi_major_axis_km":24698608.45257,"periapsis_km":null,"mass_kg":1.7259565137917085e+26,"mass_msun":0.0000868008,"constellation":"Perseus","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/toi-6041-b","radius_km":29020.355,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-6041","host_v_mag":9.838,"uncertainties":{"radius_km":[1084.277,1148.058],"distance_ly":[0.677426796517676,0.6810145166725603],"host_mass_solar":[0.036,0.042],"inclination_deg":[0.062,0.063],"host_radius_solar":[0.026,0.026],"host_temperature_k":[96,97],"semi_major_axis_km":[329115.31554,388954.46381999995],"orbital_period_days":[0.00034,0.00033]},"host_mass_solar":0.885,"inclination_deg":88.955,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.879,"planets_in_system":2,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"G7","host_temperature_k":5445,"orbital_period_days":26.04945,"periastron_epoch_bjd":2459890.1053,"transit_midpoint_bjd":2459890.1062,"equilibrium_temperature_k":605.6},"designations":[{"catalog":"Exoplanet","designation":"TOI-6041 b"}],"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.
