An asteroid larger than the Empire State Building (1,454 feet), and known as 2006 QQ23, will scream past the Earth at roughly 10,400 mph in the early hours of Saturday morning.

First spotted in 2006, hence the name, the 1,870ft-diameter juggernaut will make its closest approach to Earth on Saturday at 3:23 am EDT, according to NASA’s Center for Near-Earth Object Studies (CNEOS).

The space rock will come 10 times closer to Earth than Venus, our nearest neighbor, when it passes by at a distance of 0.049 astronomical units (4.6 million miles) while traveling at speeds of around 10,400 mph.

Any cosmic projectile with a minimum approach distance of less than 0.05 astronomical units and measuring over 460 feet in diameter is considered by NASA to be “potentially hazardous.”

The vast majority of small space objects that enter our atmosphere measure less than 30 feet in diameter and burn up on entry, but 2006 QQ23 is far larger than that.

We are currently aware of some 20,000 such Near Earth Objects (NEOs) and are discovering new ones at a rate of roughly 30 per week. Of these, we are currently aware of about 900 NEOs measuring more than 3,280 feet in diameter.

About six space objects around the size of Asteroid 2006 QQ23 pass by our planet each year, but thankfully all pose a statistically insignificant risk to life here on Earth.

The small & harmless 4 meter asteroid was detected by NOAA’s GOES-16 Satellite on the 22nd June 2019 12 hours before impact.

Although small space rocks and fragments rain down on Earth’s atmosphere continuously, experts at NASA’s Center for Near Earth Object Studies say that large events such as the one on June 22 occur about once or twice a year. Earth’s atmosphere does its job in protecting us in these cases, causing drag or friction that disintegrates most of these small objects before they strike the ground (although a few do strike, and more fall into the ocean).

Long-term weather forecast: ‘RECORD COLD’ temperatures on way as SOLAR MINIMUM begins

In 2018, the Sun has been without sunspots for 190 – or 60 percent – of days, indicating the solar maximum could be over. And NASA scientists warn that the switch from maximum to minimum has been so extreme that Earth’s atmosphere could experience “record cold”. The Sun follows cycles of roughly 11 years where it reaches a solar maximum and then a solar minimum.
 
During a solar maximum, the Sun gives off more heat and is littered with sunspots. Less heat in a solar minimum is due to a decrease in magnetic waves.
 
Martin Mlynczak of NASA’s Langley Research Center told CBN: “We see a cooling trend.
 
“High above Earth’s surface, near the edge of space, our atmosphere is losing heat energy.
“If current trends continue, it could soon set a Space Age record for cold.
 
“The thermosphere always cools off during Solar Minimum. It’s one of the most important ways the solar cycle affects our planet.”
NASA’s states on its website: “All weather on Earth, from the surface of the planet out into space, begins with the Sun.
 
“Space weather and terrestrial weather (the weather we feel at the surface) are influenced by the small changes the Sun undergoes during its solar cycle.”
 
The space agency adds on its Thermosphere Climate Index (TCI) “a weather metric that tells us how the top of Earth’s atmosphere (or ‘thermosphere’) is responding to solar activity” that “the top of Earth’s atmosphere is approximately 10 times cooler than it was during the record-setting Solar Max of 1957-58.”
 
The Sun was not expected to head into a solar minimum until around 2020, and if it is heading in early, it will mean a prolonged cold snap.
 
The last time there was a prolonged solar minimum, it led to a ‘mini ice-age’, scientifically known as the Maunder minimum – which lasted for 70 years.
 
The Maunder minimum, which saw seven decades of freezing weather, began in 1645 and lasted through to 1715, and happened when sunspots were exceedingly rare.
 
During this period, temperatures dropped globally by 1.3 degrees celsius leading to shorter seasons and ultimately food shortages.

A ‘potentially hazardous’ asteroid bigger than St. Paul’s Cathedral will zoom close to Earth tomorrow (29th August 2018)

Gigantic space rock is called 2016 NF23 and is zooming towards our planet at a speed of more than 20,000 miles per hour
A huge asteroid bigger than one of Britain’s most famous landmarks is zooming towards our planet and will reach the nearest point of its journey past Earth tomorrow. The gigantic space rock is called 2016 NF23 and is heading for Earth at a speed of more than 20,000 miles per hour – which is about 15 times as fast as Concorde. Nasa thinks the object is up to 160 metres wide, meaning it could be bigger than St. Paul’s Cathedral, which stands 111 metres high and was the tallest building in London until 1967.
 
It will pass by at a distance of about 3 million miles on 29 August and is close enough to be considered ‘potentially hazardous’. If the rock hit Earth, it would destroy an entire city and kill millions. Luckily, it’s not on a collision course with our planet so will not do us any damage. Lindley Johnson, a planetary defence officer at Nasa, told Space.com: ‘This object is merely designated a Potentially Hazardous Asteroid (PHA) because its orbit over time wings it within five million miles of Earth’s orbit, but there is nothing hazardous to Earth or even unique about this pass of the asteroid.’
 
Humanity doesn’t need to fear gigantic asteroids big enough to wipe us off the face of the Earth, because they are easy to track due to their enormous size. But we should be very afraid of smaller ‘stealth asteroids’ which are big enough to wipe out a city and extremely difficult to detect. The European Space Agency believes astronomers have spotted just 1 in 100 space rocks which are 1km wide or less.
 
Nasa figures reveal that roughly 4,300 space rocks of between 100 metres and 1 kilometre have been spotted to date. If ESA’s predictions are correct, it could mean there are actually 430,000 asteroids out there and we’ve no idea where most of them are or whether they are on a collision course with our planet. Detlef Koschny, head of the ESA near-Earth objects team, said that even small objects could do major damage. ‘If a 100-metre asteroid hit Earth, it would cause significant damage in an area the size of Germany, and even affect the surrounding region. But asteroids of this size don’t strike Earth very often. Maybe every 10,000 years on average,’ he told Space Daily. ‘Going from 100 metres down to 50 metres, the statistical frequency of strikes increases to once every 1,000 years. A century ago in 1908, a 40-metre object struck the Earth over Tunguska, Siberia, destroying an area of forest the size of the Munich metro area.
 
‘And then if we go down to asteroid sizes around 20 metres – like the asteroid that exploded over Chelyabinsk in Russia in 2013, which ended up injuring 1,500 people – these occur on average once every 10 to 100 years. We will definitely see something like that again in our lifetime.’ Earlier this year, Nasa warned of a ‘vulnerability’ in Earth’s defences which means there is only a ‘limited’ chance of spotting asteroids coming from a certain direction in space. Koschny backed up this warning, saying smaller objects are often only spotted when they pass the moon. If a large asteroid was spotted this late, it may not give governments enough time to evacuate any cities in the firing line.
