Level 6 Stars and Constellations
... If you observe a planet, say Mars, for one complete revolution, you will see that it passes successively through 12 constellations. All planets (except Pluto at certain times) can be observed only in these 12 constellations, which form the so-called zodiac, and the Sun also moves through the zodiaca ...

Homework #1 10 points Question #1 (2 pts) Even in ancient times
... Even in ancient times, astronomers knew that planets vary in brightness over the course of several months or even years. Explain, why this observation can not be used to rule out the geocentric model, in which all planets and the Sun orbit the Earth on circular orbits. Ignore the epicycles, i.e. ass ...
