Description
My Catalina Sky Survey teammate David Rankin was asteroid hunting in the constellation of Hercules when he spotted a fast moving point of light streaking through the night sky 159 million miles from Earth. David's discovery is only one of three Earth approaching asteroids discovered in 2020 which is larger than 1 km in diameter. NASA is especially interested in these very large asteroids since the impact of a 1 km or greater diameter asteroid is likely to produce global climate change.
