From north Texas last night. My first ever bright ELVE event with comet Neowise in the picture . Really exciting for me, these ELVEs are huge! hundreds of miles across. 7/16/2020 0328 UTC looking NW towards NM, CO, TX , OK border area | Paul M Smith Photography

Astronomers were watching when a comet flew past Earth on March 22 and captured radar images from the flyby. The comet was about 2.2 million miles away, making it the third closest comet flyby in recorded history. Details: http://go.nasa.gov/1Soos8E | NASA - National Aeronautics and Space Administration

When an asteroid or comet comes close to Earth we call it a near-Earth Object. But how close is close? How do we keep track of them? What can we do to mitigate our risk? We have the answers!
