Astronomers today announced the discovery of a potentially habitable Earth-sized planet orbiting the star closest to the Sun, Proxima Centauri.
Proxima Centauri is 4.24 light-years away. To put that in perspective, the Milky Way galaxy (of which our solar system is a part) is about 100,000 light years across. If trekking the Milky Way from one end to another was equivalent to walking from New York City to California, Proxima Centauri would be within the first 200 yards. So on a cosmic scale, our nearest star is extremely close.
Many people are also asking questions, such as when it was created, why it includes certain names but excludes others, whether or not statements have been cherry-picked, and what I wanted people to take from it. These are all valid questions and, with the launch of this blog, I can now answer them.
