A potentially hazardous asteroid at nearly nine kilometers per sec. flew past Earth. On collision, the asteroid easily could have destroyed an area the size of New York. According to Mail Online, the asteroid 2017 VL2 with a speed of around 5.5 miles per second was just 73,000 miles (117,480 km) from Earth. However, NASA failed to notice it and spotted it only the day after it skimmed past the planet.
On November 9, this massive space-rock flew past Earth, in Hawaii the Mauna Loa observatory, at 11:24 UTC (23:24 GMT) on November 10 observed the asteroid.
The Watchers reported that 2017 VL2 belongs to the Apollo group of asteroids. In 2125 the asteroid is expected to come close to Earth
Also , another asteroid will close to the planet on December 16 and now it is hurtling towards Earth. Named after a Greek demi-god, the asteroid 3200 Phaethon is 3-mile (5 km) wide and classified as “potentially hazardous asteroid”
NASA stated: “Phaethon is the third largest near-earth asteroid classified as ‘potentially hazardous.’ Phaethon will approach within 0.069 astronomical units (au) of Earth (an approximate distance of 6.4 million miles/10.24 m kms) on December 16 when it will be a strong radar imaging target at Goldstone and Arecibo,”
Bill Harwood (space consultant) explained it to CBS News: “Anybody that’s bigger than about 500 feet across and its orbit carry it within about 4.6 million miles of earth at any point in its orbit are classified as a ‘potentially hazardous’ object,”
“Meaning over millennia — lots and lots of time — gravitational interactions with the outer planets, you know, other objects in the solar system might perturb the orbit enough that it could actually impact the earth.”
