EPM2008 The updated model of EPM2008 includes the new values of planet masses (approved by the 27 GA IAU and close to values of DE421) and other constants, the improved dynamical model with adding the 21 largest Trans- Neptunian Objects and the expanded database (1913-2008). More than 260 parameters have been determined while improving the planetary part of EPM2008 to more than 550000 observations. EPM2008 have been oriented to ICRF by including into the total solution the ICRF-base VLBI data of spacecraft near the planets. The real uncertainty of EPM ephemerides has been checked by comparison with the observations and the JPL's DE ephemerides. Moreover at present there is access to ephemerides of the other seven bodies code named "planets - dwarfs": Ceres, Pallas, Vesta, Eris, Haumea, Makemake, Sedna those have been obtained simultaneously with the main EPM2008 ephemerides. The ephemerides of the Moon were improved by 1970-2004 LLR data. The group of George Krasinsky is now developing a lunar part of the EPM ephemerides. The new version of EPM2010 ephemerides with improved motion of planets and the Moon will be available up to close of 2010 year. The EPM2008 ephemerides cover the 1800-2198 time interval (JD 2378494.5-2523995.5) Some constants of EPM2008 ephemerides: 2446000.5 (1984) - date of the starting epoch of the integration JD 2378495.5 (12.29.1799 12h) - date of the backward integration JD 2523995.5 (13.05.2198) - date of the forward integration 299792.458 km/s - the speed of light 149597870696.547 m - number of meters per the Astronomical Unit 81.3005676536 - the Earth-Moon mass ratio 2.0*1.0D-7 - the solar oblateness 1.0 - the PPN parameter beta 1.0 - the PPN parameter gamma 0.0 - the variation of the gravitational constant 3.134 au - the radius of the asteroid ring 0.01720209895*0.01720209895 au**3/day**2 - GM of the Sun Masses GM*1.0D-15 in au**3/day**2: Mercury 49125.4957 Venus 724345.2333 Earth+Moon 899701.1347 Mars 95495.4869 Jupiter 282534584.0787 Saturn 84597060.7310 Uranus 12920248.2576 Neptune 15243591.0921 Pluto 2166.8443 Eris 2485.2618 Haumea 625.036 Makemake 908.870 Sedna 515.517 Ceres 139.726 Pallas 32.509 Vesta 38.939 Hygiea 9.633 Juno 3.831 Iris 0.990 Psyche 4.782 Bamberga 1.373 asteroid ring 25.949 (the asteroid ring additional to 301 asteroids) References: 1) Pitjeva E.V., 2008.

At present the differences between the times TT and TDB have been constructed as for EPM2004 as EPM2008 ephemerides by Valentin Panfilov. The EPM ephemerides with their TT-TDB are available to outside users via ftp://quasar.ipa.nw.ru/incoming/. The package allows a professional user to obtain in the ICRF frame the rectangular coordinates of the Sun, the Moon and nine major planets, some asteroids and TNO with regard to the solar-system-barycenter, geliocenter or a center of any planets and the Moon in the TDB time scale. The program of the access to EPM ephemerides and the user manual have been written in the Laboratory of Astronomical Programming by Olga Bratseva. Elena Pitjeva, e-mail 6 September, 2010.
