Abstract

MORGADO, Bruno Eduardo  and  SOARES, Vitorvani. Geometric construction of the Mars’s orbit by the method of Kepler. Rev. Bras. Ensino Fís. [online]. 2015, vol.37, n.1, 1305.  Epub Mar 12, 2015. ISSN 1806-1117.  http://dx.doi.org/10.1590/S1806-11173711647.

In this work we present the construction method of the martian orbit around the sun as suggested by Kepler in 1605, from the observational measurements of the position of this planet were available at that time. We show that this construction is not a simple task, and that exercise is a good teaching tool to make clear the difficulty of choosing an ellipse with very low eccentricity, instead of a circle, as the curve that describes the orbits of the planets around the sun.

Keywords : orbit of Mars; Kepler’s method.
