There's an asteroid the size of the Rose Bowl headed towards Earth. It's called Apous, named for the Egyptian god of death and darkness.
It'll have a close approach to Earth in the year 2029. It will come close enough to Earth to dip below our orbiting communication satellites. That will be the closest, largest thing we have ever observed in the history of our observing the universe.
The uncertainty in its orbit at this moment is such that for that passage, there is a range of orbits it could have, which if it goes through what we're calling the keyhole, Earth's gravity on it will be just right. That the next time it around, it will hit Earth 7 years later, April 13th.
If it goes through the center of the keyhole, it'll hit the Pacific Ocean 500 km due west of Santa Monica. It'll plunge into the Pacific Ocean to a depth of 3 miles. At that depth, it will explode, cavitating the ocean with a hole 3 m wide, 3 m deep. That impulse will send a tsunami wave that will basically wipe out the entire west coast of the United States and the east coast of Asia.
