Asteroid the size of golden gate bridge to pass by earth on January 18
A huge a kilometer-sized asteroid will fly past Earth later this month, according to NASA's asteroid tracker, marking the first flyby of an asteroid of this scale in 2022.
If an asteroid collided with Earth, it could cause a global disaster, but this is fortunately unlikely.
This asteroid, designated 7482 (1994 PC1), is expected to have a diameter of at least 1 kilometre and a width of up to 1.3 kilometres.
That's more than four times the size of the Eiffel Tower and 3.5 times the size of the Empire State Building in New York City.
The asteroid is classified as an Apollo-class asteroid, which means that its orbit is broader than Earth's and that its orbital path around the Sun may cross our planet's.
Furthermore, NASA has classified it as a potentially hazardous asteroid.
An impact, on the other hand, is exceedingly unlikely.
According to NASA's projections, 7482 (1994 PC1) will approach Earth on January 18 at a distance of roughly 1.98 million kilometres.
The Earth's distance from the moon is around 384,000 kilometres, which is more than five times less.
This confirms NASA's previous projections, which stated that the Earth would be safe from asteroid strikes within the next 100 years.
However, if the Earth had not been so fortunate, the consequences could have been disastrous.
According to a study from Israel's Weizmann Institute of Science's Davidson Institute of Science, an asteroid with a diameter of more than 140 metres would release an amount of energy a thousand times greater than the first atomic bomb if it collided with Earth.
Something even bigger, like the asteroid Apophis, which is almost 300 metres wide, might wipe out an entire continent.
