Аннотация:A high-accurate analytical representation of the latest JPL's numerical ephemeris of Pluto, DE421 (Folkner et al. 2008), by Fourier series is obtained. The maximum difference between barycentric positions of Pluto given by the new analytical series and the numerical ephemeris over 1900-2050 (the entire time interval covered by DE421) is 1.3 km. To get Pluto heliocentric positions, a development of heliocentric coordinates of the Solar system barycenter to Poisson series is made. The heliocentric positions of the barycenter given by the new analytical series and by DE421 numerical ephemeris differ by less than 5 km over 1900-2050.
