NASA confirmed that asteroids will not be a danger to Earth for 100 years. This is good news for people worried about the end of the world. NASA has been checking a 335-metre asteroid called Apophis for 17 years. They thought it could be dangerous. They put it on their list of the most dangerous asteroids. They thought it could kill over 10 million people. They said it could hit Earth in 2068. Their latest prediction is that Earth will be safe for the next 100 years.

The scientists used radar to predict the asteroid's path. A scientist said: "We were able to acquire incredibly precise information about its distance to an accuracy of about 150 meters." Apophis is now 10.6 million miles away from us. It will come within 20,000 miles of Earth in 2029. Another scientist was glad Apophis is no longer dangerous. He said he was looking forward to the science scientists might uncover from it.
