Planets (Planets)
. The planet represents the star without light in itself, but it reflects the sunlight shines into the eyes; Each Planet Moon With the size and number of the Moon satellite. away from the Sun is a different distance, and the Sun. By rotating around itself khotronop The Sun. The speed varies from a story about the planet using Earth as the main dividing
.
The planet is a planet that has no light in itself is not the same as the Sun, or stellar lighting which can be manually, but we can see the planet because the reflective planet from the Sun. There are up to 8 lights (excluding the Earth), but we can see it with naked eye only 5 Moon, mercury. Venus, Mars, Jupiter and Saturn, only that the ancient people called the five planets, The Stars, "Wandering" or "Planetes" in Greek, and to get the Sun and the Moon, two moons, "The Two Great Lights", which is when all the lights 7. In week 1, I
Entire planet 8 can be divided into groups as follows:
1. Broken down by physical characteristics
- In-class planets (Inner or Terrestrial Planets): Is a group of planets that are closer to the Sun than the other is a cool planet has more than a solid surface like Earth surface layer of Terrestrial Planets, we have called (meaning "on the surface of the Earth"), mercury (Mercury), Venus (Venus), The world (Earth) and Mars (Mars), which uses a bar of asteroids (Asteroid Belt) is a horizontal break
- Icy Planet (or Outer Jovian Planets): Is a group of more than Sunday klaiduang the planet to another is a main belt asteroid that was just cool the surface layer is covered with mostly gas, like the surface of Jupiter, called Jovian Planets (Jovian. Means similar to Jupiter): Jupiter (Jupiter), Saturn (Saturn), Uranus (Uranus), Neptune (Neptune),
. Image shows the average distance of the planet outside layer from the Sun by the Light Hours refers to the length of time the light from the sun comes to the planet (an hour) and Astronomical Units refer to distances in astronomical units (AU)
. 2. split by political circles orbit:
- Had planets (planets Interior) means that the planet is closer to the Sun than mercury, Venus and Earth
? -Planets (planets Superior), the outer circle represents the planet Earth to the next: Mars Jupiter Saturn Uranus Neptune
3. Broken down by the following surface characteristics
-Planet Rock: Mercury Venus Earth and Mars and the Moon surface, 4 solid rock. There is a thin atmosphere wrappers. But this mercury is closer to the Sun as possible, there are no nice
. -Gas planets such as Jupiter Saturn Uranus and Neptune is a gas across a small Moon rock to the seafloor might be inside surface is covered with methane gas atmosphere, ammonia, hydrogen, and helium
.(For Pluto, which has not been concluded as yet, because they are far away from the world so much)
. In addition, we know that the planet will revolve around the Moon's own orbit thati. Each of the planet's axis tilt (vertical motion scenes). Not the same. In addition, when comparing the direction of rotation around itself. Each of the planets discovered that Venus (Venus), Uranus (Uranus) will rotate around itself differently than any other planet in the solar system, the universe of us
