Asteroid (7482) 1994 PC1 which is 1.1 kilometers in diameter, three and a half times as tall as the Eiffel Tower, will speed by the Earth on January 18 at a safe distance of 1.2 million miles. Nobody expects 7482 (1994 PC1) to hit Earth. The rock orbits the Sun once every 1.57 years crossing Earth’s orbit approximately once every 30 years. The space rock will be traveling at a speedy 43,754 miles per hour. It was first seen by Robert McNaught from the Siding Spring Observatory in Australia on August 9, 1994. For this particular asteroid, if its trajectory does bring it on a collision course with Earth in the distant future, the result would be devastating. It isn’t expected to come this close again for another 200 years.
The US space agency is keeping a close eye on the giant space rock. It’s been added to its ‘Close Approaches’ list. Is unlikely this asteroid to be visible with the naked eye, but amateur astronomers with a small telescope should be able to spot it. In September this year, during the DART mission, a NASA spacecraft will deliberately crash into an asteroid to change its motion in space , testing technology developed to deflect an asteroid hit. This will happen because an asteroid has the potential to cause destruction of species or complete planet. Numerous scientists spend hours every day to track thousands of such rocks.
