Many astronomers look to the nearest stars, in the hope that they harbor a warm, wet planet like Earth. Unlike Earth, which is orbiting the Sun, there are billions of rogue planets roaming the Milky Way not bound to any host star. But don’t worry. So even an “invisible” rogue planet could act as a gravitational lens – or micro-lens, as they can be so small. This rogue planet would likely be moving at hundreds of km per second. If another star passes within ~1 Earth-Sun distance from the Earth, then there is a good chance that the Earth would wind up being ejected into interstellar space. This planet is currently being pulled by the gravitational force at our galactic center, but if it came close enough to our sun it could be sucked into its gravitational pull. The short answer is no. Conspiracy theorists are claiming that a rogue planet named Nibiru will disrupt earth’s orbit this Sunday and bring about a series of catastrophic earthquakes that could bring forth the apocalypse. Of course, if the planet formed from a collapsing cloud, it might not have had an orbit to lose. And what if it was on a collision course with us? If the earth were flung out of the solar system, it would rapidly become far too cold for any unprotected life to survive on the surface.
