Asteroids and comets arrive in the vicinity of Earth quite often, but are usually too small to cause any damage. Acting as an exception, the Asteroid 2019 GC6 will pass through Earth on April 18, at a distance of approximately 1.36,000 miles. Although this distance is safe enough not to cause any damage, it is actually closer to that of the Earth.

It is estimated that the asteroid GC6 is 42-92 feet in diameter, which is equivalent to the size of a small building. It will fly at a speed of 3.5 miles per second, about 2,000,000 kilometers from Earth. It will be harmless this time, but that may change in the future, with NASA estimating a collision in the next 100 years.
It was discovered by astronomers at the Catalina Sky Survey in Arizona. Scientists at NASA's Jet Propulsion Laboratory have put it on the list of asteroids that can hit Earth in the next century. Even a small asteroid accident around an area of civilization can have terrible effects, like the one in 2013 that exploded near the Russian city of Chelyabinsk, adding tons of radioactive material to Earth's atmosphere. This 20-meter-wide asteroid affected more than 1,500 lives in its vicinity, with a 30-times-larger impact than the Hiroshima atomic bomb.
Studying its current speed and orbital trajectory, it is expected that the CG6 will pass through Earth again in 2034, 2041 and 2048. For reference, a lunar distance is equal to 3.84,400 km, which is the average distance between our Earth and the Moon It will be very difficult to detect inherently because of the distance from us, a dark color and no tail (only comets have this).
