A large "potentially hazardous asteroid" is expected to swing fewer than six lunar distances from Earth at the beginning of next month. 

The asteroid, known as 2022 RM4, is expected to pass by Earth on Nov. 1 – about 1.5 million miles away at its closest point.

According to NASA's Center for Near Earth Object Studies, the asteroid has an estimated diameter of between 330 and 740 meters, or up to over 2,400 feet.

It will pass by the blue planet at around 52,500 miles per hour, according to LiveScience. 

STUDY SAYS ASTEROID THAT KILLED THE DINOSAURS ALSO CAUSED A GLOBAL TSUNAMI

Any space object that comes within 120 million miles of Earth is deemed a "near-Earth object." 

Any large body within 4.6 million miles of Earth is classified with the astronomical term: a "potentially hazardous asteroid." 

2022 RM4 is also an Apollo-type asteroid, which is a class of objects named for asteroid 1862 Apollo.

NASA'S DART MISSION SUCCESSFULLY HITS ASTEROID INTO NEW ORBIT

Such asteroids have an orbit that is larger than Earth’s orbit around the sun and their path crosses Earth’s path. 

2002 RM4 orbits the Sun every 1,397 days and its path does occasionally cross Earth’s orbital path around the Sun.

According to NASA, Earth faces no known danger from an apocalyptic asteroid collision for at least the next century.

In addition, the agency's Double Asteroid Redirection Test (DART) spacecraft recently redirected the non-hazardous asteroid Dimorphos by sending it off course.
