A scientist explained how astronomers and space agencies such as NASA can track rogue asteroids that have the potential to hit Earth. These planets also might be drawn into orbit around black holes, which have stronger gravity than stars do. If a sizable rouge planet hit one of the rocky planets such as Mars, large chunks of debris would come shooting out of the collision, a very high chance that a few pieces would land on Earth potentially creating another mass extinction; similarly to the other rocky planets such as Venus and Mercury. “If the lens were orbiting a star, we would detect its presence in the light curve of the event,” adds Dr. Poleski. Unlike Earth, which is orbiting the Sun, there are billions of rogue planets roaming the Milky Way not bound to any host star. “We can rule out the planet having a star within about 8 astronomical units (the astronomical unit is the distance between the Earth and the Sun).” The rogue planet is not bound by gravity to any star.
