Moon-Sized Exoplanet

For a long, long time all we humans could do in the quest to find exoplanets, planets out side of our solar system, was to look for large planets that had a noticeable impact on their host stars. This left us with only the ability to find gas giants and super massive Earth-like planets, but now we've found a planet no bigger than our own moon. This little hunk of rock orbits close to its star and has a surface temperature of over 700 degrees Fahrenheit, but it is a step closer to finding an Earth-like planet beyond our own planet. I find this very exciting. For more information, check out this article.
