The ten-mile asteroid collided into present-day Mexico at 66 million years, nearly obliterating life on Earth. However, the impact of the collision was almost as severe as the initial impact, according to the studies – and with another massive cosmic rock toward Earth, the study should serve as a stark warning. The asteroid, known as the 1990 MU, is currently completing another orbit of the Sun and may reach dangerously close to Earth in 2027.
Asteroid 1990 analysis is between 4-9 kilometers in diameter and on June 6, 2027 it will be "close to Earth", according to a NASA analysis.
The asteroid will be only 0.03 AU from Earth, the only astronomical width of our planet's hair.
An AU is the distance between the Earth and the Sun, so arriving within just 0.03 AU is dangerously close.
For reference, Mars – the planet that humans hope to reach – is about 0.5 AU.
The asteroid is classified as a potentially dangerous asteroid that NASA has "the potential to make threatening close approaches to Earth".
If the asteroid hits Earth, which NASA claims is extremely unlikely, it would have global consequences – and research has found that if it hits the water, humans will not be safe if the last collision with a monster asteroid is something go to.
A study found that a dinosaur-destroying asteroid known as the Chicxulub asteroid causes such devastation that the largest tsunami on Earth ever seen is the result of a shock.
Research from the University of Michigan has found that the impact is so intense that a tsunami can be seen in all the oceans on the planet.

The first showed the initial devastation of the impact, which showed a wave extending up to 1,500 meters in height, which is the "initial explosion of water away from the impact," according to Ms Range.
The second simulation showed that the water filled the crater, which probably caused more massive waves.
Brian Arbich, a physical oceanographer at the University of Michigan, said: "You have a steep water wall running back in."
The simulations also showed waves spread around the world over several days.
The research paper states: "The tsunami impact spread rapidly from the Gulf of Mexico into the Atlantic Ocean and across the Central American Sea Route into the Pacific within the first 24 hours.
"This model suggests that the impact of the car has not only had major effects on the global atmosphere and the biosphere, but also created a tsunami of such magnitude that its effect is felt in much of the oceans."
Mr Arbich said: "It must have been one of the biggest tsunamis ever."
