NASA has predicted 31 potential dates between 2019 and 2101, on which the asteroid threatens to hit the Earth. The closest impact date, which also happens to be the most likely date of cataclysm, falls on December 28, 2019.
A GIANT asteroid measuring more than 4,100ft in diameter risks striking the Earth on December 28, 2019, if it suddenly veers off-course, NASA’s asteroid trackers have warned.
The asteroid, dubbed Asteroid 2010 GD37, is next most likely to crash into Earth on December 21, 2093. The asteroid also threatens to hit Earth in December 2022, December 2024 and December 2027.
Even SWAT Teams are Helpless Against This…
NASA’s terrifying predictions are based on 19 observations made between April 5, 2010, and April 9, 2010.During this brief period of analysis, the US space agency calculated the asteroid’s diameter and mass as well as its barreling speed.
According to NASA’s Jet Propulsion Laboratory (JPL), Asteroid GD37 measures roughly 4,137ft (1.261km) across.The asteroid also weighs in at an incredible 2.7 trillion kg or 2,700,000,000,000kg.
Because of this, NASA believes the asteroid packs a devastating impact force of 260,000 Megatons (Mt).Just one megaton is the equivalent of 1,000 Kilotons (Kt) or 1,000,000kg of TNT, meaning GD37 could hit Earth with the force of 260,000,000,000kg of TNT.
NASA-If an asteroid is indeed going to come very near the Earth then a collision cannot be ruled out early on.
For comparison, the nuclear bomb dropped on Hiroshima in 1945, had a blast force between 13Kt to 18Kt or 13,000 to 18,000 tonnes of TNT.And at the point of atmospheric entry, Asteroid GD37 would likely hit the Earth at a velocity of 64,088.225mph(28.65km per second).
But what exactly is the risk of Asteroid GD37 striking Earth this year or on any of NASA’s other 30 risk dates?
Thankfully, the danger is minimal and will likely remain so unless some force pushes the asteroid out of its orbit and into Earth’s path.

On December 28, 2019, there is an impact probability of 0.000000070 percent.This means there is a one in 1,400,000,000 odds of cataclysm or a 99.99999993 percent chance the asteroid will miss.
A devastating crash is even less likely to happen on the next most likely impact date in 2093.
Asteroids like GD37 are tracked by NASA’s Sentry systems, which keep a watchful eye on all cataclysmic asteroids threatening Earth.
The US space agency said: “Sentry is a highly automated collision monitoring system that continually scans the most current asteroid catalogue for possibilities of future impact with Earth over the next 100 years.
“Whenever a potential impact is detected it will be analysed and the results immediately published here, except in unusual cases where we seek independent confirmation.”
“The impact probability will tend to grow as the orbit is refined and alternative and safer trajectories are eliminated.
“Eventually, the impact probability will drop, usually quite abruptly, to zero or, if the asteroid is really on a collision trajectory, it will continue to grow until it reaches 100 percent.”
As new observations and orbital calculations are made, NASA often removes objects from its list of threats.

And the good news is NASA currently knows of no object, which directly threatens the safety of the planet in the foreseeable future.

How often do asteroids hit Earth?
According to astronomer Lynn Carter of the Smithsonian Institution in Washington DC, it is hard to say exactly how many space rocks pelt the Earth but there are some indicators.
Astronomers estimate the average number of meteors and asteroids which hit Earth by calculating how many hit a certain area over the course of one day.
Dr Carter said: “Another way to tell how many meteorites hit Earth each year is to look at the number of meteorites found in dry regions where there isn’t much vegetation or erosion, where you expect to be able to find most of the meteorites that fell.
“We can get an estimate of how long ago the meteorite fell to Earth by looking at how it’s been weathered, or altered by Earth’s atmosphere and the local climate.
“Then we can plot how many meteorites fell at that region per year.”
On average, studies suggest between 18,000 and 84,000 meteorites bigger than 10 grams reach the Earth each year.
