Venus is the second closest planet to the Sun and is the second brightest object (at max.) in the night sky after the Moon. In Greek it is often called «Αυγερινός» (morning star) ή «Αποσπερίτης» (evening star). When Venus is visible for about three hours after the sunset it is called Evening star and when it is visible for about three hours before sunrise it is called Morning star. It has a similar size compared to Earth but its atmosphere presents completely different characteristics. The goal of the scenario is for students to be able to calculate the Sun-Venus and Earth-Venus distances through scientific methods.
