AT SCHOOL: TALKING ABOUT JUPITER.

Teacher: Good morning, students! Have you studied today!

M.: Yes, teacher!

Teacher: ok, let’s start with the questions:  Which planet has the composition similar to the Sun?

Manuel: : It’s Jupiter, because it consists mainly of hydrogen and helium with small quantities of other compounds, such as ammonia, methane and water. It is believed that the planet possesses a multi-layered structure, with a solid core. I like this planet because it is  known since ancient times, has played a predominant role in the religious belief of numerous cultures, including the Babylonians, the Greeks and the Romans, who identified it with the ruler of the gods. The planet’s astronomical symbol is a stylized representation of lightning, the main attribute of that deity.

T.: What can you say about its  external atmosphere?

M.: It  is characterized by numerous bands and zones of shades varying from cream to brown, dotted with cyclonic and anticyclonic formations, among which the Great Red Spot stands out.

T.: Why does it seems to be a flattened spheroid?

M.: Because of its rapid rotation that generates an intense magnetic field that gives rise to an extensive magnetosphere; moreover, due to the Kelvin-Helmholtz mechanism, Jupiter (like all other gas giants) emits more energy than it receives from the Sun.

T. why has Jupiter  been considered a “failed star”?

Manuel: in reality only if it had had the opportunity to increase its mass up to 75-80 times the current one, the its core would have hosted the conditions of temperature and pressure favorable to the triggering of the reactions of fusion of hydrogen into helium, which would have made the solar system a binary star system.

T: that’s good….last question:  Are there any satellites?

Manuel:yes, lots of  satellites and a barely visible ring system orbit around Jupiter.

T: excellent!
