The discovery of the New Planet Earth Resembles

Recently, a team formed by 73 astronomers from various countries to ensure that they have discovered planets like Earth are the smallest in the outer solar system. Planet of the most similar to Earth outside our solar system until recently, its surface covered by water possible. Planet orbiting the star Gliese 581, located 20.5 light-years away in the constellation Libra. The scientists found the planet using a special telescope in Chile.


They say the temperatures are warm and comfortable on the planet it means the planet's surface is filled by water, which theoretically can sustain life. Things like this planet 28,000 light years distance away, and the sun is a red dwarf star that is not high, therefore the temperature at the planet's surface roughly ranges between 220 degrees Celsius below zero.

Based menyandarnya fixed stars, the scientists who discovered the planet named OGLE-2005-BLG-390Lb, is the same fixed star like our sun, located in the galactic system. During these 11 years, has more than 170 planets found beyond the galactic system, but most of them larger than the Earth. They are generally very large volume such as the planet Jupiter, and is not easy if you want to watch, they can only be seen when passing through the fixed stars.

However, because of the influence of gravity can make the star's light curve, causing the observed phenomena that are not stable, when observing the volume of the smaller planet, the impact is not so big. By 1912 Einstein had suggested the phenomenon of micro lenses lensing, and because of this theory too, then to find a planet like earth. The definition of micro-lensing is a fixed star in the line of sight, gravity makes the line remains distant star's light or views of planets other earth-like planets close together, giving rise to the phenomenon of an increasingly bright.

OGLE-2005-BLG-390Lb magnitude 5.5 times that of Earth. Distance with a fixed star disandarnya own as far as 390 million km, and this distance if it is in the galaxy, roughly located between Jupiter and Mars. Evolution of the circulation around a loop fixed star, ie, one year it was, spent 10 years of the earth.
