Asteroid 163348 (2002 NN4) is expected to zoom past Earth at 12:50 pm (IST) on Sunday this week.
It is larger bigger than about 90 percent of asteroids, according to Buzasi, who also likened it to a football stadium.
According to the NEO Close Approach data table, which documents near-Earth objects and the dates they approach our planet, asteroid 2002 NN4 will make its closest approach to Earth on June 6, at 3:20 a.m. UTC, and at its closest will reach a distance of 3.16 million miles to Earth.

NASA is tracking a giant asteroid which may be taller than the Empire State Building in the U.S., and it will be flying near the Earth on June 6 (Saturday).
While it is unlikely for an asteroid to strike anytime soon, scientists gathered at a 2019 conference to discuss how to respond to one massive enough to obliterate a major city.
While the chances of a major asteroid hitting Earth are small - NASA believes there is a one in 300,000 chance every year that a space rock which could cause regional damage will hit - the devastating prospect is not impossible.
NASA is keeping track of three giant asteroid set to skim past Earth in June.
"It doesn't really keep me up at night", Glaze told the network. There are now 958,621 known asteroids, according to NASA.
Another asteroid named 2013 XA22 will breach the MOID on Monday, June 8 at 3:40 p.m. UTC and coming within 1.8 million miles of Earth, will be significantly closer than 2002 NN4.
An asteroid - or any other space object or debris - is classified as "potentially hazardous" when it comes within 7.48 million kilometres of Earth.
The asteroid will whiz by the earth at a distance of more than 10 times further than the orbit of the moon.
It has a diameter of 570 metres, making it our biggest visitor this month; it's classified as a "potentially hazardous Near-Earth Object".
