Gliese 581C, the 3rd planet orbiting around the red dwarf star Gliese 581, is the most earth-like planet yet to have been found outside the solar system. With a mass 5 times that of earth, a gravity of 1.6G, and a temperature between 0 and 40 degrees celsius, it orbits around its star every 13 days. With stargazing being a strong Indian tradition, it's amazing to think that we have now passed the era of searching for stars, and have now moved on to the era of searching for other earths. Only time and more investigation will tell if Gliese581C harbours enough water for life.
