If a black hole came close to Earth, it could heat the planet, evaporate oceans, and make life uninhabitable.A black hole is an almost invisible object with gravity so strong that even light cannot escape. The consequences of such an object entering the Solar System depend on several factors, including the black hole's size and distance, according to Live Science. Known black holes are either stellar-mass black holes (several to 100 times the mass of the Sun) or supermassive black holes (100,000 to billions of times the Sun’s mass), typically found at galactic centers.If a stellar-mass black hole or larger were to pass through the Solar System, it could cause catastrophic events depending on its proximity and speed. For instance, if it passed through the Oort Cloud—the most distant region of the Solar System—it could disrupt the orbits of comets and asteroids, sending them hurtling toward Earth, explains Karina Voggel, a postdoctoral researcher at the Strasbourg Astronomical Data Center in France.
