Asteroid the Size of 3 Blue  Safely

Whales Zooms Past Earth

An asteroid the size 

of three blue whales just zoomed past Earth, but don't worry, Earthlings were not at risk from this space rock.

The asteroid missed the

 planet by more than 2.2 million miles, about 10 times the moon-Earth distance, at its closest approach

 The asteroid, known as

 2021 GT2, is between 121 and 272 feet (37 to 83 meters) wide, which means it could wipe out a city, if it were to hit Earth.

2021 GT2, hurtling 

through space at a mind-boggling speed of 16,000 mph (26,000 kph), is a so-called Aten asteroid

2021 GT2,

 discovered last year, orbits the sun every 342 days and is one of 1,800 Aten asteroids currently known. 

The next "close" encounter

 between 2021 GT2 and Earth will take place in January 2034. That encounter will pose no risk to Earth either
