“Just 39 light years?” Why it must be just around the corner. Gliese 1132b: Astronomers find a super-Earth that may have a watery atmosphere, just 39 light-years away – LA Times
39 light years, for people who don’t understand astronomical distances (like the person that came up with this headline), is a really long way.
Light travels at approximately 300,000,000 meters per second. So 1 light year is 9.461 X 1015 meters or about 5.879 trillion miles. Times 39. And you use the word “just.”
This planet is 229.3 trillion miles away. A little less than 12 parsecs. (Notable because Han Solo referenced that number in Star Wars: A New Hope.) Or for those of us who prefer to use scientific notation for science, 3.69 X 1017 meters.
