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-1080-b","name":"TOI-1080 b","class":"terrestrial_planet","category":"exoplanet","object_type":"Terrestrial planet","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":83.36230858062245,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":276.3683249,"dec_deg":-52.214573,"epoch_ra_deg":276.904566,"epoch_dec_deg":-52.19958,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1080","semi_major_axis_km":4069062.0830399995,"periapsis_km":null,"mass_kg":6.390219618536775e+25,"mass_msun":0.0000321373,"constellation":"Telescopium","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/toi-1080-b","radius_km":7653.72,"radius_kind":null,"data_quality":"The published mass and radius imply a density no material has.
