The asteroid, known as the 1990 MU, is currently completing another orbit of the sun, and by 2027 it could be dangerously close to Earth. Asteroid 1990 MU has a diameter between 4 and 9 kilometers and is set to an astronomical unit of 0.03 AU on June 6, 2027. An AE is the distance between the Earth and the Sun, so it's dangerous to get within just 0.03 AU.
For reference, Mars – the planet people want to reach – is about 0.5 AU.
The asteroid is classified as a potentially dangerous asteroid, which according to NASA has the "potential to threaten the earth".
According to NASA, 2019 was OK in size – an estimated width of 187 to 427 feet (57 to 130 feet) – and quickly raced along a path that has brought it to just 45,000 miles (73,000 km) from Earth in recent weeks as it flew by.
This was less than a fifth of the distance to the moon and what the professor of the Royal Institution of Australia, Alan Duffy, described as "unpleasantly close."

An asteroid strike 66 million years ago put an end to the dinosaurs
This asteroid would have been big enough to wipe out a city, and 1990 MU could really be devastating.
Asteroid 1990 MU has a diameter of up to nine kilometers and is thus in the same ball park as the space rock, which puts an end to the dinosaurs.
It is believed that the space rock was between 10 and 15 kilometers wide and plunged into present-day Mexico 66 million years ago, marking the beginning of the end of the dinosaurs.
Research at the University of Glasgow has shown that up to three-quarters of Earth's life was eradicated by the asteroid and dinosaurs die out within a matter of centuries.

The space rock caused a cloud of dust to fill the air that blocked the sun, resulting in drastic and sudden climate change that ultimately led to a large food shortage on Earth that led to the death of larger animals and allowed smaller creatures such as mammals to thrive in their absence ,
Now controls a comparable asteroid to the earth.
While the asteroid will be close in the next ten years, it will be even closer in 2058 if it is within .02 AU – less than three million kilometers.
Scientists estimate that an end-of-life asteroid, such as the one that ended the dinosaur's reign, would collide with Earth approximately every 100 million years.

The hunt for asteroids
But asteroids can strike at any time and there is always a very small chance that a massive space rock ending in civilization will strike earlier.
For that reason, many argue that global authorities should have a plan – but apparently not.
NASA colleague Robert Frost, who according to his biography works on Quora's Q + A website as a flight instructor and flight controller for the space agency, said governments could only advise the public to "squat" because there was very little can be done to prepare for the inevitable.
Mr. Frost wrote in response to the question, "If it were discovered in two months that an asteroid would annihilate humanity, how would the governments of the world react?"
The value of asteroids
He said, "This is a tough question, movies tell us they would keep it a secret, it has a lot of meaning, mass panic can be more dangerous than the actual event.
"But my experience in government is that the government is really not good at keeping something secret, unless it starts in a secret part of the culture, like the military.
"Something like that is probably first discovered by someone who can not spell" security clearance. "It would be obvious to astronomers around the world.

"When we felt helpless, the government probably just told us to kneel down and tape our window seams.
"Then Democrats would accuse Republicans of ignoring global warming, and Republicans would blame the Democrats for not praying at school."
