Asteroid DANGER: a scientist admits that we miss 100,000 KILLER asteroids | Science | New



Space is a dangerous place, harboring deadly radiation, inhospitable temperatures and unimaginable pressures. And even the Earth is not immune to extraterrestrial hazards, because very occasionally, our planet is muted by deadly asteroids. Now respected space scientist, Bill Nye has revealed that initial prospects could be even worse than feared, with thousands of asteroids out there to be identified.

Most asteroids are very small and those less than 10 meters in diameter simply burn up when they warm the atmosphere of the Earth.

We are missing potentially one hundred thousand killer asteroids

Spatial rocks 25 to 45 m in diameter will cause a major collision resulting in the erasure of cities or even whole counties.

Asteroids ranging in size from 100 to 140 m could make an entire country disappear, and larger ones as known as continent killers.

Although these asteroids of even greater dimensions cause the death of entire breeds of species.

The American scientific personality Bill Nye revealed "that we are missing potentially one hundred thousand killer asteroids".

The famous American science commentator said on AsapSCIENCE on YouTube: "We want to build a spacecraft called Sentinel Craft.

"Search for asteroids, it's like looking for a charcoal briquette in the dark; these things are hard to find.

"These asteroids are tiny compared to the vastness compared to the vastness of space.

"But infrared light and heat bounce off those asteroids.

"Thus, the surveillance spacecraft are placed back to the sun and look from the orbit of Venus."

Once such a murderous asteroid finds itself sneaking through a collision with Earth, Mr. Nye explains how they can be deflected.

He said: "We have to deflect these asteroids from a tiny amount.

"An asteroid can travel 10 km / s and we want to change its speed by about 2 mm / s.

"This will change the speed of the asteroid of a 10 millionth of its total.

"But asteroids can contain between 10,000 and 100,000 tons, which requires considerable force to modify it 10 million times faster.

The founding member of the Planetary Society then explains the simplest way to achieve this change of trajectory.

Bill Nye said, "The easiest way is to place a big rocket in a collision course with the killer asteroid.

"It would change his speed a bit."

However, that would not solve the problem if the asteroid was actually a pile of rocks connected by gravity.

Because such a collision would simply cause the rocks to spread out, resulting in a deadly rain of space rocks.

The only possibility, he explains, is to launch an even bigger spacecraft and send it near the asteroid.

"The mutual gravity of the asteroid and spacecraft will pull the asteroids lightly," he said.

However, he says, this plan has its own disadvantage.

"We would need a huge amount of fuel for years.
