      Could asteroids crash into Earth?
      NASA Most asteroids in the solar system orbit in the main belt, between Mars and Jupiter and never come close to Earth. But others, through billions of years of gravitational do-si-do, have been slung into other orbits. Some of those now cross paths with Earth’s orbit, and thus potentially could crash into Earth someday.

      Was there an asteroid threatening the Earth?
      There was an asteroid, but it wasn’t threatening the Earth. And there was a spacecraft, relying solely on sophisticated technology. The human heroes of the mission were actually at a physics and engineering lab between Baltimore and Washington, D.C. And there was a collision.

      What asteroid will fly past Earth in 2029?
      On April 13, 2029, Apophis, a 1,100-foot-long asteroid, will fly less than 20,000 miles above Earth’s surface, closer than the orbits of geosynchronous satellites — meaning it will be visible to the naked eye. Asteroid 2024 MK will fly past Earth on June 29. It is between 400 and 850 feet across and will pass within the orbit of the moon.
