Seven planets in the Milky Way that have environmental conditions similar to Earth.

Search for life in outer space does not seem to need to reach planets beyond our galaxy, the Milky Way. Seven planets in the Milky Way has a huge potential to life after the researchers conducted an ambitious project that is able to do the cataloging planet can be inhabited.

Catalog Planets or The Habitable Exoplanets Catalog (HEC) is celebrating its first anniversary by announcing that the current expectations of the discovery of Earth-like planets already exceeding their expectations.

According to lead researcher Professor Abel Mendez, the discovery of five additional planets could be inhabited from the two that have been found to greatly exceed their expectations.

“There are so many releases that announced the discovery of a can be inhabited planet … and it’s confusing. So have a catalog where everyone can examine whether the planet is can be inhabited at the moment is a useful thing,” said Mendez.

There are about 80 planets outside our solar system (exoplanets) with a size similar to Earth but only a few of the planet that has the right distance from their star in the solar system. Distance is needed to support the existence of water on the surface is needed to sustain the existence of life.

The catalog compiled using indicators like the Earth Similarity Index (ESI), Zone Distance Allows to Live (HZD), the classification system, Global Primary Habitat (GPH) and comparison with the Earth in the past and present.

Currently seven of potentially can be inhabited planets are in the list of HEC. Meanwhile, about 27 planet candidates NASA’s Kepler team is awaiting confirmation.

All superterran aka planet earth is in a larger size. Although larger planets are believed to have the potential to live. Until now, researchers have not found a planet that has as terrestrial environments.

Nevertheless HEC declared all planets still require advanced astronomical observations. There is no assurance that such planets could be inhabited by humans.

Seven planets are likely to be inhabited:

1. Gliese 581d
2. HD 85512b
3. Kepler 22b
4. Gliese 667Cc
5. Gliese 581g
6. Gliese 163c
7. HD 40307g
