2. Duh Mercury • Mercury is the first planet of our solar system and next to the Sun, it is to only 0.387 astronomical units (UA) but has an eccentric orbit of 0,20. Form leaves from rocky inner planets and its diameter is of only 4,879 km. To the being so small and next to the Sun it is difficult to locate it from the Earth. • Mercury is a planet that has a very tenuous atmosphere and therefore, with the last images of the space probes that have happened through the planet have observed a surface similar to the spot by the immense amount of craters that there are in his surface

3. Venus is the second planet from the sun, and considered in many ways to be a twin planet earth. It has a similar size, mass, density and gravity, as well as a very similar chemical composition. In other ways, Venus is very different than Earth, with its high surface temperature, crushing pressure, and poisonous atmosphere. Duh Venus • In terms of size, Venus is quite similar to Earth. Its radius is 6,052 km (95% the size of the Earth). Its volume is about 86% the volume of Earth, and its mass is 4.87 x 1024 kg, which is about 82% the mass of the Earth. The gravity on Venus is 90% the gravity on Earth, so if you could actually walk around on the surface of Venus, the gravity would feel very similar to Earth.

4. Duh Earth • It is the home of human beings and other living things. Why can this planet support life? The earth is a sphere covered with rock, water, soil and air. It is just the right distance away from the sun. We all need sunlight and warmth for life. If the earth was too close, it would be too hot for living things and if it were too far, it would be too cold. • The earth is the fifth largest planet and the third planet from the sun. Its diameter is 8,000 mile long.

5. Duh Mars • Mars is about half the size of our planet, Earth. It's thin atmosphere is slowly being blown away by the sun’s solar wind .However, its atmosphere forms clouds, and sometimes supports planet-wide dust storms. • The red planet has many features that are visible to the backyard observer with a powerful enough telescope. First of all, Mars has a reddish color due to the iron oxide - commonly known as rust - that is in the soil.

6. Duh Jupiter • Jupiter is a gas giant. This means that it has a huge atmosphere, a liquid mantle, and a liquid / solid core, with no definite boundary between the layers • The core of Jupiter is probably composed of liquid rock, at a temperature as high as 24,000 K (43,000 °F). The core is small relative to the planet, about 20% of its radius, but it is still fifteen times heavier than the Earth. • The layer on top of this is ordinary liquid hydrogen. This composes the upper 25% of the planet.

7. Duh Saturn • Saturn is a gas giant. It's structure is very similar to Jupiter. The core is composed liquid rock. Next comes a layer of liquid hydrogen. It is under such high pressure that the nature of the hydrogen changes, and is able to conduct electricity like metal. This generates the planet's magnetic field. • The layer on top of this is ordinary liquid hydrogen. Next, the hydrogen thins out into the gaseous atmosphere. It is composed of mainly hydrogen and helium with trace amounts of methane, water, ammonia, and hydrogen sulfide.

8. Duh Uranus • Uranus was the first planet to be discovered in modern history. It was actually discovered by accident in 1781 by William Herschel.

9. Duh Neptune • Neptune, like its twin, Uranus, has an atmosphere composed of hydrogen, helium, methane, and ammonia. The methane creates the blue color. Neptune's internal structure is also the same as that of Uranus. • The core of Neptune is probably composed of liquid rock. Then, farther up, the liquid rock slowly gives way to an ocean, primarily containing hydrogen, helium, and water, but also ammonia and methane. This "ocean" accounts for most of Neptune's bulk. The ocean slowly thins out into the atmosphere.

10. Duh Pluto Pluto is perhaps best characterized by its history in astronomical and popular culture. After Uranus was discovered, tiny changes in its observed orbit could not be accounted for by the gravitational effects of the other planets. The end result was that another planet was theorized to exist, and it was discovered to be Neptune. Additional perturbations were then found to Neptune's orbit in 1905, and this created the idea that there should be an additional planet beyond Neptune.
