It's the first day of a new month in the year 2022 and the fascinating show by asteroids continues unabated! And yes, there is an asteroid today heading for a close approach with Earth. NASA confirmed a new “potentially hazardous” asteroid making its closest approach to Earth today on April 1, that is today any time soon. According to the NASA’s Centre for Near-Earth Object Studies (CNEOS), the near-Earth object named 2007 FF1 is said to be around 120 metres to 260 metres wide, which is as big as a multi-storey building. This asteroid today, will fly by Earth from a distance of just 4,610,000 miles. The asteroid has been classified as “potentially hazardous” by NASA. Besides this, it is an Apollo-class asteroid, that are the near-Earth objects whose orbit crosses the orbit of Earth.

Actually, NASA's Centre for Near-Earth Object Studies keeps track of asteroids that have the potential to collide with Earth. That would be a catastrophe and could destroy humanity forever. NASA tracks almost 1,000 asteroids that have passed close to Earth since 1968. And when an asteroid with a diameter of more than 150 meters approaches Earth, NASA classifies it as a potentially hazardous asteroid and monitors it closely. Hence, NASA classified Asteroid 2007 FF1 as potentially hazardous.

The upcoming building-sized asteroid 2007 FF1 had also made its closest approach back in 2020, the NASA's Jet Propulsion Laboratory said. According to NASA, anything passing near Earth's orbit is called a Near-Earth Object (NEO). Also, it needs to be located at a distance less than 1.3 times the distance from Earth. It has been monitoring tens of thousands of NEOs to know whether they can be hazardous for Earth or not.
