A Planets is a large space object which resolves around a star. It also reflects that **star light**. Eight planets have been discovered in our solar system.Mercury,venus earth,and mars are the planets closest to the sun. They're called the **inner planets**. Most of us grew up with the conventional definition of a planet as a body that orbits a star, shines by reflecting the star's light and is larger than an asteroid. Although the definition may not have been very precise, it clearly categorized the bodies we knew at the time. In the 1990s, however, a remarkable series of discoveries made it untenable. Beyond the orbit of Neptune, astronomers found hundreds of icy worlds, some quite large, occupying a doughnut-shaped region called the Kuiper belt. Around scores of other stars, they found other planets, many of whose orbits look nothing like those in our solar system. They discovered brown **dwarfs**, which blur the distinction between planet and star. And they found planetlike objects drifting alone in the darkness of interstellar space.The planets was discover in the libra and also discover with only three times the mass of the earth.

 * SUBTOPIC:MARS**

Mars is a planet closest to the sun.The temperature on mars can be very, very cold. On its warmest day,Mars can still be very cold place. At the top and the bottom of the planet are poles just like on earth.During the **Martian winter**, ice caps can be seen at the poles.Mars is the fourth planet from the Sun and is commonly referred to as the **Red Planet**. The rocks, soil and sky have a red or pink hue. The distinct red color was observed by stargazers throughout history. It was given its name by the Romans in honor of their god of war. Other civilizations have had similar names. The ancient Egyptians named the planet //Her Descher// meaning //the red one//.

**The Planet charts**

//**Jupiter**//:The fifth planets from the sun and is the largest one in the solar system. It contain more matter than all of the other planets combined.
 * QUICK FACTOIDS**:


 * Venus**:The second planets from the sun and sixth largest.Venus'orbit is the most nearly circular of that any planet.

//**Mars**//:The planet closest to the sun.The temperature on mars can be very,very cold.On Its warmest day,Mars can still be a very cold place.


 * Saturn**:The sixth planets from the sun and is the second largest in the solar system with an equatorial diameter of 119300 km.


 * Uranus**:The solar system and the planet uranus,the seventh planet from the sun,was discovered by William Herschel on March 13,1781.

 * Neptune**:is times the mass of the earth and slighly more massive than it near twin Uranus,which is 15 Earth masses and as dense.
 * Planets** have always been defined by their dynamics. The word "planets" comes from the Greek word for "wanderer", an object that moves across the background of the fixed stars.
 * **Moons** have always been defined by their dynamics. A moon is an object that moves around (orbits) a planet. There are moons that look round and there are moons that don't look round at all. Their shape is irrelevant to the classification.
 * A classification based on dynamics is far easier to implement than a classification based on physical properties. Newly discovered objects can be classified immediately, long before the details of their physical properties are known.
 * We already classify other objects in our solar system based on their dynamics, such as the near-Earth asteroids (Aten-Apollo-Amor), the Trojan asteroids, the Centaurs, the trans-Neptunian objects (**resonant-scattered-classical**).
