GARMS, Marco Antonio  e  CALDAS, Iberê Luiz. Kepler's laws synthesis. Rev. Bras. Ensino Fís. [online]. 2018, vol.40, n.2, e2316.  Epub 30-Nov-2017. ISSN 1806-1117.  http://dx.doi.org/10.1590/1806-9126-rbef-2017-0253.

The aim of this paper is to present the conception of the laws of planetary motion using the free softwares Stellarium and Geogebra to get and process data similar to those accessible to Kepler. Although this procedure is not exactly equal to the one accomplished by Kepler, it allows, in a didactic way, to understand and to apply the orientation followed by him in order to obtain his laws about the planetary motion. It is expected that the quantitative study here developed make clear the meaning of some qualitative discussions in several references on this subject and have didactic application.

Palavras-chave : Kepler's laws; elliptical orbit; Mars; planets; solar system.
