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 like planets that have similar kinds of signatures. What makes Kepler so unique is that it can use select criteria to determine which planets are in line with these objectives. While at the same time, it is segregating those bodies that are considered to be false positives. This is illustrating how science has evolved to the point that 8 different earth types of planets have been discovered in other galaxies. To fully understand what is taking place requires examining the different discoveries. This will be accomplished through looking at: the surface temperature, planetary mass, star type, its distance from Earth and known masses of companion planets. Together, these different elements will provide the greatest insights as to the significance of these discoveries. (Seager 1 -- 15)

Gliese-58d

Gliese-58d has a surface temperature of between 0 and 40 degree Celsius. The planetary mass is about five times as large as the earth. The star type is the known for being M. class body (Galiese-581). This is about 100 billion years old. It has a red dwarf sun and is located inside the Libra constellation. The distance of the plant to Earth is 122 trillion miles. Its distance from its sun is approximately 322 million miles. The orbit of the planet is considered to be circular in motion (with the celestial body completing an orbit of the sun every 37 days). The other companion planets in this solar system include: Gliese-58c and Gliese-58g.
It has similar earth like temperatures that are able to sustain life and they contain water. As a result, it does belong on a list of earth like planets. This means that there is the possibility it can be able to sustain basic and intelligent life forms. (Lloyd 106 -- 115)

Gliese-58g

Gliese-58g has a temperature of between 0 and 40 degrees Celsius. The planetary mass is considered to be three times larger than Earth. The star type is the known for being M. class body (Galiese-581). This is about 100 billion years old. It has a red dwarf sun and is located inside the Libra constellation. The distance of the planet to the Earth is approximately 123 trillion miles. Its distance from the sun is about 350 million miles. The other companion planets in this solar system include: Gliese-58c It has similar earth like temperatures that are able to sustain life and they contain water. These elements are showing how it does belong on a list of earth like planets. Therefore, there is realistic possibility that it can sustain basic and intelligent life. (Lloyd 106 -- 115)

HD-5512b

HD-5521b is the only planet that is orbiting the star known as HD-5512. The approximate temperature is about 47 degrees Celsius. The mass of the planet is .69 the size of Earth. The likely age of the star is about 25 billion years old and it located in solitary star. Its distance is approximately 250 million miles from the sun. As a result, this is only planet in this solar system that is known for having the conditions of being able to sustain life. The basic orbit is considered to be cylindrical in nature. This means that it qualifies as an earth like body that is capable of sustaining basic and intelligent life. ("A Habitable Planet")
