New analytical planetary theories VSOP2010
Abstract
The planetary theories VSOP are essentially issued from the research works of P. Bretagnon. After the last version, VSOP2000, he began to make some improvements, but, unfortunately, he did not have time to complete his work. We took up again this work introducing various changes and complements and build two versions : VSOP2010A fitted to DE405 (numerical integration of the JPL) and VSOP2010B, not yet finished, fitted to INPOP08A (numerical integration of the IMCCE at Paris observatory). Over the time interval [1890,2000], the estimated precision is 3 to 10 times better than that of VSOP2000. Over the time interval [-4000,8000], the gain in precision is about 5 times better for the telluric planets and 10 to 50 times better for the outer planets in comparison with VSOP2000.
