IIT Bombay students discover closest known asteroid to fly by EarthAugust 2020
On August 16, an SUV-sized asteroid soared just 2950 km above the surface of Earth. IIT Bombay students Kunal Deshmukh and Kritti Sharma, working on a research project, discovered this object just hours later using data from the robotic Zwicky Transient Facility (ZTF) in California. Designated 2020 QG, it is the closest known asteroid to fly by Earth without impacting the planet. The previous known record-holder is asteroid 2011 CQ1, discovered by the Catalina Sky Survey in 2011, which passed above Earth about 1,550 miles (2,500 kilometers) higher than 2020 QG.
