Exoplanets are planets outside the solar
system. Started in 1992 with the first discovery, astronomers have found a
planet around 837 in 660 planetary system around the milky way until now .The
researchers believe that they will find many more planets in this year and a
study in 2012 estimates that every star from the 100 billion or so in the Milky
Way Galaxy has average 1-6.
Most of the discovery of Earth-like Exoplanets
are not identified, they have characteristics closer to Jupiter or Neptune or
gas giant.
Planets like earth are likely to exist in outer space, but astronomers had to find it in teh habitable zone are quite closeto the star that there is water in liquid form, but not tooo closely because it is too hot for life. A dozen exoplanets have been found in the habitable zone and teh spacecraft using the space telescope to identify 54 candidates other exoplanets.
