An asteroid almost as large as the Great Pyramid of Giza will pbad Earth closer than the moon tomorrow.
The space rock, called 2019 OD, has a diameter of up to 120 meters and travels at a speed of 19.17 kilometers per second (42,882 miles per hour), according to NASA.
It will pbad Earth at a minimum distance of approximately 219,748 miles, which may seem like a long road, but it is closer than the Moon, counting as a close scratch in astronomical terms.
2019 OD is actually one of the three asteroids that will make an "approach" to Earth tomorrow, according to NASA's Center for Near-Earth Object Studies (CNEOS).
A much smaller asteroid the size of Nelson's Column, known as 2019 OE, will pbad 2.5 times the distance of the Moon (601,917 miles).
Another large asteroid, known as 2015 HM10, with a diameter of up to 110 meters, will also pbad a distance much greater than 2,914,043 miles.
NASA said there are currently no known asteroids with a significant probability of impacting the Earth in the next century.
However, NASA chief Jim Bridenstine warned that a killer asteroid could crash into Earth in our lives, unless we do more to protect the planet.
Speaking at the 2019 Planetary Defense Conference in Washington earlier this year, the NASA administrator warned against the so-called "giggle factor" when it comes to asteroids.
"We have to make sure that people understand that this is not about Hollywood, it's not about movies," Bridenstine said.
"It is ultimately about protecting the only planet we know, right now, to house life, and that is planet Earth."
NASA has already detailed its plans to remove an asteroid from the course by sending a spacecraft to deliberately crash into it.
The mission, called Double Asteroid Redirect Test (DART), aims to demonstrate NASA's ability to divert any space rock that is in the process of collision with Earth.
The space agency expects to launch the spacecraft in June 2021, with the aim of colliding with an asteroid known as Didymoon in October 2022.
