Where were you in the solar system a month ago? The answer: 49 million miles from where you are right now. That’s the distance Earth travels every month in its orbit around the Sun. Pretty amazing, isn’t it? Across the last 49 million miles, one constellation has continued to slink along our southern horizon. That’s Hydra the Water Snake. Last month, we surveyed the western half of Hydra, while this month, we’ll focus on the constellation’s eastern half.
