NASA said asteroids will not be a danger to Earth for 100 years. Some people worried about the end of the world. NASA has been checking a 335-metre asteroid called Apophis. In 2004, they thought it could be dangerous. They thought it could kill over 10 million people. They thought it could hit Earth in 2068.

The scientists used radar to look at the asteroid's path. They got very precise information about its distance. Apophis is now 10.6 million miles away from us. It will come within 20,000 miles of Earth in 2029. Another scientist was happy that Apophis is no longer dangerous. He said he was looking forward to studying it.
