An asteroid four times the size of the Empire State Building will approach Earth on May 27. (CNEOS).
7335 (1989 JA) will miss Earth by 2.5 million miles (4 million kilometres), or 10 times the distance to the moon.
NASA has labelled the asteroid as "possibly hazardous" because of its size (1.8 km) and proximity to Earth. If its orbit ever changes and it impacts Earth, it may cause major damage.
The next near flyby will be June 23, 2055, 70 times the distance between Earth and moon.
NASA monitors more than 29,000 NEOs each year, including this asteroid. NASA defines NEOs as astronomical objects that pass within 48 million kilometres of Earth's orbit.
NASA says 7335 (1989 JA) is bigger than 98% of NEOs it tracks.
