In this section of Cosmos, you can calculate accurately the ephemeris for the major celestials bodies of the solar system, with some advanced choices.
The ephemeris data available for this calculation are:
- DE405 of JPL ( Jet Propulsion Laboratory ), that allow you to compute calculations between the 9th December de 1599 AD (00:00:00 hours)  and the 20th of February of 2201 AD (00:00:00 hours) - TDB time. These are the most accurate ephemeris ever made.
- DE200 of JPL that allow you to perform calculations between the 9th December of 1599 AD (00:00:00 hours) and the 2th May of 2169 AD (00:00:00 hours) - TDB time.
- DE406 of JPL allowing you to get results between the 23th February of 3001 BC (00:00:00 hours) and the 6th May of 3000 AD (00:00:00 hours) - TDB time.
- DE431 of JPL - allow to get results between December 9th 13002 BC (00:00:00 hours) and January 11th of 17000 BC (00:00:00 hours) - TDB time.
- DE408 of JPL/Dr. E. Myles Standish  - one of the last theory of JPL/NASA, that allow you to perform calculations between the 1st November of 10002 BC (00:00:00 hours) and the 6th February of 10000 AD (00:00:00 hours) - TDB time.
- DE601 of JPL/Dr. E. Myles Standish - ( BRAND NEW ) the last accomplishment of Dr. Standish. This particular theory allows for computations between the 12th September of 98237 BC (00:00:00 hours) and the 27th of September 58807 AD - TDB time. An astonishing solar system integration of our dearest friend.

The results - if you maintain checked the option Reduced (apparent - are corrected for light time effect, aberration and relativistic deflection of light due to the gravitational field of the Sun.
