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":"tic-260969020-b","name":"TIC 260969020 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":395.3732841957907,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":74.9407148,"dec_deg":-79.5859489,"epoch_ra_deg":74.504725,"epoch_dec_deg":-79.544304,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TIC 260969020","semi_major_axis_km":null,"periapsis_km":null,"mass_kg":3.338441838095381e+25,"mass_msun":0.0000167895,"constellation":"Mensa","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/tic-260969020-b","radius_km":14203.174799972001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TIC 260969020","host_v_mag":12.393,"uncertainties":{"radius_km":[1227.765689729,1521.823270435],"distance_ly":[1.2263479802149553,1.2328711077692902],"host_mass_solar":[0.102434,0.068286],"inclination_deg":[1.36136,0.80416],"orbital_period_days":[0.00004440555,0.00004786981]},"host_mass_solar":0.75,"inclination_deg":88.75946,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.68988,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":4572.94,"orbital_period_days":8.48584501953,"transit_midpoint_bjd":2458631.52270935},"designations":[{"catalog":"Exoplanet","designation":"TIC 260969020 b"},{"catalog":"Host star","designation":"TIC 260969020"}],"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.
