Astronomy 302. The Inner Planets

 Vamos a la segunda clase del tercer año de Astronomía y empezaremos a aprender características sobre los planetas. Esta lección la dividiremos en dos partes: Los planetas más cercanos al sol y los planetas más lejanos (También podemos hablar de planetas pequeños y planetas grandes

Después dela teoría haremos un diorama con todos los planetas al igual que el año pasado,pero este año usaremos una caja de zapatos para presentarlo

Aquí os dejo un vídeo para que veáis como se puede hacer

Para ello necesitamos:

- una caja de cartón

- papel o cartulina negra para el fondo y purpurina para decorar

- bolas de polispan de diferentes tamaños

- palillos chinos para sujetar los planetas mientras los decoramos

- temperas o pintura acrílica de varios colores

- rotuladores para decorar 

As mentioned last year, each planet reflects a significant amount of magic to us.  The strength of this magic depends upon its size, among other things, so we begin our discussion about the planets by touching on their diameters.  The planets, in increasing order of distance from the Sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune

The planets are divided into two groups: the inner planets and the outer planets.  Since we are going to describe the planets in increasing order of distance from the Sun, we will discuss the inner ones first.

Astronomy 302. The Inner Planets

The inner planets, also called the Rocky Planets are Mercury, Venus, Earth, and Mars, and they are separated from the outer ones by the asteroid belt. They all have rocky surfaces and are much smaller than the outer ones, but they reflect just as much magic to us because they are closer to both the Sun and Earth

Mercury, the innermost planet, has no moons, but its surface looks like that of Earth’s Moon, with mountains, plains, and craters. It has a very thin atmosphere. It’s made up mostly of oxygen, sodium, and helium. The sunlit side of Mercury can reach temperatures as high as 427°C, whereas the temperature

Venus, which, like Mercury, has no moons, is covered entirely by a thick layer of clouds made mostly of sulphuric acid. Venus’s atmosphere is made up of mostly carbon dioxide with a bit of nitrogen. The temperature is extremely hot, night and day and all over the planet’s surface, reaching about 462°C, even hotter than Mercury. Because Venus is almost the same size as the Earth, they are often called sister planets

Earth will be studied in great detail in following years, so I won’t get into too much detail here

Mars’s surface, like Mercury’s, also has mountains, plains, and craters. It looks reddish because of the iron oxide that covers most of the planet and is blanketed with dust. Additionally, while there is no liquid water on the surface of Mars, some was discovered underneath the surface, leading to speculation that life may once have existed there and possibly still does. Its atmosphere is made up of mostly carbon dioxid. The temperature ranges from -143°C at the poles to as high as 35°C at the equator at Martian noon, when the Sun is highest in the sky. Mars has two moons, Phobos and Deimos
