It look this week is a specially busy one in the space around our planet . NASA ’s Center for Near - Earth Object Studiesreports that 11 objects will be fly past Earth before Sunday . None of them is a jeopardy that warrants worry .
The closest object is 2019 SL7 , flying 571,443 km ( 355,078 miles ) past Earth . This is about 40 percent further out than the Moon . The objective is between 18 and 40 meter ( 59 to 131 infantry ) in diameter , slightly larger than the objective that explode over the Russian metropolis ofChelyabinskin 2013 .
If such an physical object were to return to Earth , it would likely produce ravaging at a local stage , although its exact extent would count on its concentration and whether or not it hits the earth . For example , the Russian bolide blow up at an altitude of 29.7 kilometers ( 18.5 miles ) , with the shock wave herculean enough to damage over 7,200 construction , including the roof of a factory .
The furthest target to pass by Earth is 2019 SE2 . At its closest approach , it will be 7.7 million km ( 4.8 million miles ) away . The object will also be one of the bighearted in the group , with estimate ranging from 41 to 92 measure ( 135 to 302 metrical foot ) . A potentially self-aggrandizing object is 2019 SX5 , with its size ranging from as large as 140 meter or as “ small ” as 62 meters ( 459 to 203 feet ) . Such an physical object could cause devastation at a regional level , but luckily it will get no closer than 7.15 million klick ( 4.442 million miles ) .
Eleven asteroids flying " stuffy " to our planet might seem like a lot , but it ’s common for there to be a fistful of space rocks move about . What ’s a moment more odd is to have a large number of these airless encounters known well in approach .
Last September 21 , nine near - Earth object fly close to our satellite . Yet on the day , we only cognize about four of them ; two of these fours were discovered just the day before . The other five objects were discover in the day follow the secretive pass . Such upshot proceed to show just how much we still do n’t know about the pocket-sized objects of the solar organisation .
