Question

keplers first and third laws quick check
which planets orbit was kepler first studying when he began to develop his laws of orbital motion? (1 point)
○ saturn
○ jupiter
○ mars
○ earth

Explanation:

Johannes Kepler began his work on developing the laws of orbital motion by studying the orbit of Mars. Tycho Brahe's detailed astronomical observations of Mars' orbit provided Kepler with the data he needed to analyze and eventually formulate his laws, as Mars' orbit had noticeable deviations from circular motion that could be studied to understand planetary orbits better.

Answer:

Mars
