JOHANNES KEPLER, THE MAN WHO OPENED THE DOOR TO SPACE

15. May 2018  -   "400 year - 3rd Kepler Law - ANNIVERSARY"

Why do we know when Kepler discovered his 3rd law ?

Because he wrote about this lucky day in his life in his famous book "Harmonices Mundi"


In his 5th book, "De Motibus Planetarum" ........


...... on page189 you can read the date.

Following I have marked it in the Latin written text.

The Bavarian Academy of Science and Humanities in Munich.  has published a collection of all Kepler books.

In this collection there are new, and better readable prints. I have marked the important Latin written text.


Above a German written translation and remark on this page showing the same facts .....

Doubtlessly, today we know about the importance of Johannes Kepler's laws for calculating orbits from planets or even spaceships.

So proudly we can say: 


Kepler-Remote-Observatory - a local project to honour Johannes Kepler
