Astronomy The Terrestrial planets are defined as rocky planets or telluric planets, and they are Mercury, Venus, Earth and Mars. These planets have a lot of similarities that allow them to be grouped together, especially in contrast to the Jovian or gas planets. The telluric planet is one given type of planet, defined as one that is primarily composed of rocks and heavy metals. Thus, the composition of these planets is

Earth Like Solar Planets Throughout the course of human history, astronomers have wondered about the possibility of finding life beyond the solar system. In the last 20 years, there has been more of an emphasis on identifying other earth like celestial bodies that are orbiting distance stars. This has been taking place through the launch of various orbital telescopes such as: Kepler. Monitoring over 150 thousand stars, Kepler is identifying earth

Extra-Solar Planets The word planet means "wanderer" in Greek. It derives from the fact that planets within our solar system seem generally to wander eastward about the so-called fixed stars across the zodiac constellations (Kolb). There is no clear consensus precisely defining what constitutes a planet, as distinguished from brown dwarfs, which are the material remnants of burned out ancient stars whose masses where too small to form white dwarfs or

Introduction One of the key components of post-Earth survival for humans is transforming another planet or celestial body to be fit for human habitation through supporting human life. The transformation of another planet is commonly referred to as terraforming, which is a term that refers to human colonization of space. Terraforming the planet is associated with some advantages in addition to the potential to support human life/habitation such as contain biosphere

life form found on Mars would be like. Mars is the fourth planet from the sun, while Earth is the third, so the planets are relatively close neighbors. However, the environments on these two planets are extremely diverse. Earth is a planet where life has evolved, while Mars is a barren planet devoid of life. However, if life could survive there, it would be extremely different from what we
