However, time is running out to forecast the asteroid's risk, as it will fly behind the sun in April, where it will be out of view of most telescopes on Earth, which will limit how much predictions can be refined, he said.
"Any observations we can make between now and when it's out of view will obviously help us to refine the orbit and to make better predictions," said Lewis. "That doesn't necessarily mean that it will go down before April. It could continue to go up, but still ultimately miss us."
NASA has designated the asteroid as a level three on its Torino Scale since late January, reports The New York Post.
