2. How Far Away Are They?
The short answer: about 40 light-years away. If you’re not a physicist, you may be slightly unclear on what a light-year is. If you guessed a light-year was super duper far away, you guessed right. Light is the fastest moving object in the Universe and can travel six trillion miles in the space of one year. In other words, these planets are about 240 trillion miles away from us. So at present, that’s a pretty unfathomable distance away. So what makes this find so monumental?
