2008 GO20, the asteroid's size has yet to be conclusively determined, but estimates place it between 97 to 220 meters, or 318 to 720 feet as large as the iconic Great Pyramid of Giza in Egypt is set to fly close to the Earth today, according to NASA, but should safely pass by without impacting the planet. On July 31, another asteroid, dubbed 2019 YM6, will also approach the planet – this one being even larger than 2008 GO20, though will be even farther away.
