The 700-meter scale – called the Asteroid 1998 HL1 – will cross the earth between October 25-28. The asteroid is classified as a potentially dangerous asteroid (PHA). It was first discovered by astronomers on the Lincoln Near Earth Asteroid Research Project (LINEAR) in Socoro, New Mexico, in 1998.
But NASA charts reveal exactly how close to "near" skip ".
The HL1 will travel at a staggering speed of over 25,000 mph as it barges past our planet.
Since discovered, 1998 HL1 has been observed up to 408 times.
If hit the Earth, an asteroid of this size would cause catastrophic damage.
The closest approach to the Apollo asteroid this year will be 1
The flight is incredibly close in astronomical terms (1.6AU) – but fortunately it won't hit the earth for at least 120 years.
If ever hit the earth, the asteroid is big enough to kill millions of people.

H e: "We need to make sure that people understand that it's not about Hollywood, not for the movies.
"This is, after all, the defense of the only planet we currently know to host life – and this is planet Earth. ”
NASA is currently in the process of developing a dual asteroid (DART) test.
When completed, the DART system will check whether it is possible to redirect asteroids that threaten to affect Earth.
The latest HL1 news comes after NASA acknowledged a "sneak to us" asteroid last month closer to our own moon. century.
The rock invaded the past almost unexpectedly, causing concern among astronomers.
Lindley Johnson, Planetary Defense Officer, wrote in an email to the staff: "This one slipped over us and this is an interesting story about the limitations of our current exploration network. "
However, NASA continues to assert that" no one should be too concerned "about the impact of an asteroid or comet.
NASA's JPL website states: it poses a significant risk of impact on Earth over the next 100 years . "
