are 8 planets in our solar system; these are divided into two types‚ large gas giants (Jupiter‚ Saturn‚ Uranus and Neptune) and smaller rocky terrestrial planets (Mercury‚ Venus‚ Earth and Mars). The order from closest to the Sun outwards is; Mercury‚ Venus‚ Earth‚ Mars‚ Jupiter‚ Saturn‚ Uranus and finally Neptune. Until 2006 Pluto was also classed as a planet‚ however it is now classified as a dwarf planet (meeting the first two requirements of the definition but not the third). A planet is currently

Planet Venus and Earth are often called twins because they are similar in size‚ mass‚ density‚ composition and gravity. However‚ the similarities end there. [Photos of Venus‚ the Mysterious Planet Next Door] Venus is the hottest world in the solar system. Although Venus is not the planet closest to the sun‚ its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms up the Earth. As a result‚ temperatures on Venus reach 870 degrees F (465 degrees C)‚ more than hot

All planets except Mercury and Venus have at least one moon. Saturn has the greatest number of moons—18. In 1995‚ the Hubble Space Telescope detected what appeared to be four additional moons of Saturn; however‚ that discovery has yet to be confirmed.

Planets of our Solar System The Earth: The earth is the fifth largest planet of the solar system. The life is possible on the earth because its gravity is sufficient to hold atmosphere and best conditions for sustaining life. It contains a large amount of water in the form of oceans. 71% parts of the total area is covered with water and the remaining 29% is covered with land. The temperature of the centre of the earth is 2000° C. The circumference of the earth is 40‚000 km. The earth completes

The Title of Planet Must be Given Back Voting done at the International Astronomical Union convention about pluto’s status of being a planet was a harsh new reality‚ with the majority voting for pluto’s demotion. Professor Alan Stern‚ chief scientist for the New Horizon mission set for learning more about pluto‚ called the outcome "an awful decision" and described the new definition as "internally inconsistent" ("Why Is Pluto No Longer a Planet?"). The debate of pluto being a planet has started

limits of our solar system there is a planet unlike any other‚ Pluto. Pluto was discovered in February of 1930 by an American astronomer‚ Clyde Tombaugh. It is the only planet to have been discovered by an American. All though we have known of the existence of Pluto for over thirty years now‚ there are still many mysteries surrounding this celestial body. Being the farthest planet has made it difficult to study Pluto‚ Adding to the obscurity of this strange planet is that the capability to send spacecraft
