Some asteroid is a whoping 2 x106km from Planet Earth. It moves at speed of 10 km/s. Without gravitation pull, this asteroid would miss Earth by a perpendicular distance 25,000 km from the center of Earth. What is the closest the asteroid can be to Earth? Does it hit Earth? If not, will it come back to Earth again?
