she said NASAA “potentially hazardous” asteroid will fly past Earth tomorrow, and the asteroid, named 2015 FF, is expected to come within 0.02864 AU, or about 2.6 million miles, of Earth’s surface, and the FF has a diameter of 42 to 92 feet (13 to 28 meters), meaning it is The average size of a blue whale (90 feet) or almost three times the length of a London bus.
According to the British newspaper, “Daily Mail”, when 2015 FF passes Earth, it will travel at 9.1 km per second or 20,512 miles per hour, which is almost 30 times the speed of sound.
Despite being 10 times the distance from the Moon, the asteroid is classified as a Near Earth Object (NEO) and is being tracked by the space agency.
2015 FF is a “potential hazard” because it is within 0.05 AU (4.65 million miles) of Earth, although the observable 2015 FF on NASA’s website is 2.6 million miles away, which is astronomically relatively close, and perhaps for this reason, 2015 FF is limited by NEO. , although it is not expected to be harmful.
A NEO is an asteroid or comet whose orbit brings it to or through a region between about 91 million and 121 million miles (195 million km) from the Sun, meaning it will pass within about 30 million miles (50 million km) of Earth. can Around the circular path.
