A COLOSSAL asteroid measuring almost one mile in diameter could potentially veer off-course and slam into Earth as early as December 28, 2019, NASA has warned.
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. 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.
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).
If an asteroid is indeed going to come very near the Earth then a collision cannot be ruled out early on
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.
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?
