In the English vocabulary, the word nemesis has come to mean downfall or ruin, and surely nothing good can result from a celestial body bearing this moniker. The Nemesis Theory: Is There a Second Sun in Our Solar System? Every twenty-six million years the orbit of Nemesis brings it through the Oort cloud, a mass of comets and debris out on the far reaches of space. Nemesis disrupts the comets, sending them hurtling toward the inner planets in a rain of destruction that can last decades. Comets smash into Earth and cause these mass extinctions at a regular and predictable rate. Nemesis may not have the same size and power as our sun, and it's not likely to come anywhere near the Earth, but it has enough of a push to cause havoc from afar. The bad news is, if Nemesis exists, it is coming, and our planet will be forever altered. Maybe someday we’ll have some kind of defense against a barrage of comets crashing down to earth, but as for right now, we may as well enjoy the night sky without worrying too much about what might be hurtling at us.

It was first serendipitously observed in November 2010, when it was a whopping 3 billion miles from the Sun, which is nearly the average distance to Neptune. Since then, it has been intensively studied by ground and space-based telescopes.
