We're going to talk about the little-known things about these two stars.

We will start with nuclear reactions, does it sound familiar proton-proton, triple-alpha or CNO? We will also see spectacular photos of the Sun and some of a total eclipse. As well as planetary traffic. We will discover what an analemma is and how to capture it.

As for the Moon, we will first check whether it rotates or not, then whether it is liar or not, or what apparent differences it has between the apogee and perigee. We will know at what speed its shadow moves on Earth and what rotation speed our planet would have without it. By closing, we will see its relations with popular culture and who were the first travellers to tread on it.

Curiosities that you might already know but that you had not think about it.
