Understanding > End of the section

You arrive at the end of the section "Understanding"

 You have followed the order given by the sigh  and arrived at the end of "Knowing more" of the section "Understanding" of the present site. You have seen the usefulness of the positional astronomy for the definition of calendars and the computation of ephemerides, you have understood some fundamental concepts useful for the understanding of the Solar system and you have learnt more about some notions especially related to Solar system bodies.

We propose now, to close the tour in the Solar system, a glossary of words and terms used in positional astronomy and in celestial mechanics and, following, some help to teach all this knowledge to pupils and students.
