The Milky Way Contains at Least 100 Billion Planets According to Survey →
Kailash Sahu, of the Space Telescope Science Institute in Baltimore, Md., is part of an international team reporting today that our galaxy contains a minimum of one planet for every star on average. This means that there is likely to be a minimum of 1,500 planets within just 50 light-years of Earth.
The study concludes that there are far more Earth-sized planets than bloated Jupiter-sized worlds…A rough estimate from this survey would point to the existence of more than 10 billion terrestrial planets across our galaxy.
