AT SCHOOL: TALKING ABOUT VENUS.

Teacher: Giulia, what can you say about Venus?

Giulia: it is classified as terrestrial planet. Venus   is the brightest natural object in the night sky after the Moon and for this reason it has been known since ancient times. Its discovery is very interesting… Venus is visible only shortly after sunset and just before sunrise and for this reason it was often called by the ancient Greeks (and later by the Romans) the evening star or morning star.  Teacher, I like the history of its origins. It was probably discovered  in the West by Pythagoras, but it would have been due to the astronomers of Mesopotamia. In the Tablet of Venus by Ammi-Saduqa, in fact, observations dating back to 1550 BC are reported. or antecedents, in which no distinction is made between the star of the morning and that of the evening.

T.: why is it referred to as  the “twin planet” of the Earth?

Giulia: mmm. I don’t know.

Sebastiano: because it is very similar to the earth in size and mass. However, in other respects it is quite different from our planet. The atmosphere of Venus consists mainly of carbon dioxide and is much denser than the Earth’s atmosphere, with a pressure at ground level of 92 atm. The density and composition of the atmosphere creates an impressive greenhouse effect that makes Venus the hottest planet in the solar system.

T.: That’s good!  has the planet any satellites?

G.: no, it hasn’t. 

T.: excellent!
