Titanic-sized asteroid to fly by Earth this weekend.

An asteroid, roughly the same size as the Titanic, is set to pass by Earth this weekend. The asteroid, named 2023 NZ1, is estimated to be between 200 and 426 feet in diameter and will come within 3.5 million miles of Earth. NASA has classified it as a "potentially hazardous asteroid" due to its size and proximity to Earth.
