The Goldilock Planet and Zone

Introduction

People have always wondered that there would be earth-like planet out there in the universe. This planet would have life on it or water which is the basic necessity for having life. Recently in 2004, this myth started to become a fact when Astronomers in the United States discovered two more planets the size of Neptune orbiting stars outside our solar system. The planets were smaller even than the one discovered by the European Space Agency. Both these two new planets were detected by the Doppler Effect. However, scientists warned that although the new planets approaching the size of Earth, its other features could be very different. Perhaps in the very distant future, humans would discover that their knowledge of physics is obsolete, from there, they could begin to have any hope of learning about other forms of life on extra-solar planets (Garlick, Pp. 140-106).

Origin of the term

The term Goldilock was developed in the mid 1990s to describe the positive performance of the economy as "not too hot, not too cold; just right". A term developed in the mid 1990s to describe the positive performance of the economy as "not too hot, not too cold, but just right". Furthermore, in astronomy it is called extra-solar planet or exo-planet, a planet orbiting a star other than the Sun and therefore, not in the Solar System. Extra-solar planets became a subject of scientific research in the nineteenth century. Many astronomers supposed to exist, but there was no way of knowing how common they were or how similar they might be to the planets of our solar system. The first detection was confirmed in 1992 with the discovery of several planets orbiting the Earth (Miller, Vandome & McBrewster, Pp. 4-47).

Mars and Venus not potential Goldilocks planets

The planets Mars and Venus have been known and reported since antiquity. Observation of Mars is particularly difficult because Mars, a bright red "star", which can be seen in the sky. The red color, the most characteristic feature of Mars, is the color of dust and rocks that cover the surface of the planet. An analysis of Martian soil, carried out by the two Viking spacecraft that landed on Mars in the summer of 1976, showed that the soil contains a lot of iron (Moore, Pp. 44-95). It seemed that conditions on Mars allow the existence of life, but in reality it is a world of cold and dead (hence, not a potential Goldilock planet), while Venus is easily visible. It is, after the Sun and the Moon, the brightest celestial body. Like the moon, goes through a series of phases - from a narrow crescent to full. However, it is different from the Earth. It has no oceans and thick atmosphere causes a greenhouse effect that raises the temperature to 480 ° C. It's scorching, therefore, not a potential Goldilock planet (Simon, Pp. 2-29).

Thesis Statement

A planet needs to fulfill Goldilock zone/planet characteristics in order to be a potential planet to have life on it ...
