Does Earth still have a chance? NASA issues a warning! "Asteroid Apophis is heading for Earth!" What will happen when this asteroid crashes into the sea off the west coast of the USA is shocking. Neil deGrasse Tyson warns that this terrible day is coming and that we must expect far-reaching consequences. Within a few hours, the entire west coast of the USA would be destroyed, the damage would reach astronomical levels and millions of people would have to be evacuated from coastal cities such as Santa Monica, San Francisco and Los Angeles. What else should we expect and could an asteroid of this size even destroy the entire Earth?
