Southern Arizona residents should take special note of a large asteroid that's set to zoom past Earth this week.
The rock, called 2014 JO25, was discovered by astronomers with the Catalina Sky Survey at the Mt. Lemmon Sky Center Observatory three years ago.
The group's director and principal investigator Eric Christensen said their goal is to continue to search for new, potentially hazardous asteroids.
NASA has said the rock is about the size of six football fields and will pass "close" to Earth.
The asteroid will be more than 1 million miles away but that is close for a rock this size -- it's been 13 years since such a large one came close.
Scientists said there's no need to worry as there is absolutely no chance of a collision.
You'll be able to see it with a telescope, or you can watch online HERE.
