Space rock 7482 1994 PC1 is a relative close miss at simply 1.2 million miles from our home planet - - a little north of five times the distance to the moon.

Tuesday is the day to get a brief look at a kilometer-wide space rock zooming past Earth.
It's a relative close miss at simply 1.2 million miles from our home planet - that is a little north of five times the distance to the moon - and flying at 47,344 mph, as per NASA's Center for Near Earth Object Studies.
The "span size" space rock, at 3,451 feet wide, was found in 1994 and named 7482 1994 PC1. It's been delegated a "Possibly Hazardous Asteroid" in light of its size and close flybys with Earth, in spite of the fact that it gets no opportunity of hitting our planet. Contrast that with 4660 Nereus, the 1,082-foot space rock - about the size of the Eiffel Tower - that flew inside 4.6 million miles of Earth in November, too "concerning" researchers.
Skywatchers with the right devices - preferably, a 6-inch opening or bigger telescope - can get a closeup with the vast collider at 4:51 p.m. at the point when it's closest to Earth, as sunlight might cloud its perceivability to the unaided eye during that time, as per EarthSky.com. The space rock will show up as a sluggish meteorite while the telescope is pointed at different reference stars all through the evening.
Close Earth #asteroid 1994 PC1 (~1 km wide) is very notable and has been read up for quite a long time by our #PlanetaryDefense specialists. Have confidence, 1994 PC1 will securely go by our planet 1.2 million miles away next Tues., Jan. 18.

By NASA guidelines, anything passing inside 120 million miles is a close Earth object. The current week's orbital appearance will be its nearest pass for an additional two centuries, the space office said.
Soon, NASA desires to explode the likelihood that space rocks like 7482 1994 PC1 may obliterate Earth with a new "Armageddon"- style space rock detonating plan named Double Asteroid Redirection Test (DART). In November, the DART space apparatus took off on a SpaceX rocket determined to demolish Dimorphos, a space rock 525 feet across.
