The approaching asteroid is known as 7482 (1994 PC1), and it was discovered in 1994, according to NASA.
No one expects 7482 (1994 PC1) to hit Earth, but it is the closest asteroid will come in the next two centuries, according to NASA's forecasts. The asteroid is expected to be closest to our planet at 16.51 ET.
It will not be the largest asteroid that has ever swept past Earth. That honor belongs to the asteroid 3122 Florence (1981 ET3), which flew by and failed to collide with Earth on September 1, 2017. The asteroid is estimated to be between 2.5 miles and 5.5 miles wide and it will run once again on September 2, 2057.
In September this year, a NASA spacecraft will deliberately crash into an asteroid to change its motion in space - test technology developed to deflect an asteroid hit.
Earth-like objects are asteroids and comets with orbits that place them within 30 million miles (48 million kilometers) of Earth. Discovering the threat of terrestrial objects or NEOs that could potentially cause serious damage is a primary focus of NASA and other space organizations around the world.
