is Earth the only planet in our solar system capable of sustaining life? Why is Earth the only planet in the solar system that has plentiful liquid water and an atmosphere that can protect the planet from the harmful ultra-violet rays of the Sun? What makes Earth so special? These are some of the questions that will be explored in greater detail as we use Comparative Planetology to understand what makes Earth a habitat for life and what makes it so different from the other planets in our solar system

The sun is a star. It is the star round which the earth and other planets revolve. In a way‚ we can say that sun is the head of solar family or solar system. Compared with the millions of other stars‚ the sun is a medium sized star and of average brightness. The sun appears to be larger and brighter because it is much more nearer to the earth than any other star. Thus‚ the star nearest to the earth is the sun. Though sun is the nearest star to the earth‚ even then it is at a distance of 150 x 106

Following the discovery of the planet Neptune in 1846‚ there was considerable speculation that another planet might exist beyond its orbit. The search began in the mid-19th century and culminated at the start of the 20th with Percival Lowell’s quest for Planet X. Lowell proposed the Planet X hypothesis to explain apparent discrepancies in the orbits of the gas giants‚ particularly Uranus and Neptune‚[1] speculating that the gravity of a large unseen ninth planet could have perturbed Uranus enough

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.

The debate of pluto being a planet has started

consists of the sun and nine planets. Mercury is the closest planet to the sun. Mercury was named after the Roman God of Commerce and Thievery. It might have gotten its name because of the way it quickly appears and disappears from Earth’s view. Mercury is the second smallest planet in the solar system; Pluto is the only planet that is smaller. Earth’s diameter is about 7‚200‚ while tiny Mercury has less than half of that size‚ about 3‚000 miles in diameter. Mercury‚ a planet‚ is smaller than Ganymede
