At approximately 12:14 p.m Tuesday, asteroid 2021 AF8 will be zipping by Earth at a speed of about 20,000 miles per hour (32,000 kilometers per hour). With a diameter of about 580 meters (1,902 feet), this space rock is larger than the Petronas Twin Towers in Malaysia. The two buildings, which previously held the title of being the tallest manmade structure in the world, stand at a height of almost 452 meters (1,400 feet).

Just a few hours after 2021 AF8's flyby, another big asteroid will be making its close approach to the planet. Identified as 2021 HC3, this near-Earth object (NEO) is smaller in size than 2021 AF8 at 170-300 meters (570 feet) wide. Its size makes 2021 HC3 nearly as large as the Eiffel Tower, which boasts a height of 324 meters (1,062 feet), per the Measure of Things.
