Another asteroid skims the earth – closer than the GPS satellites

If we are talking about a asteroid that passes through the parts of our planet, there are three questions that anticipate all the others: how close it is, how big it is and when the passage is expected. And luckily the answers, in this case, are all reassuring.

Two weeks ago, asteroid 2022 EB5 was discovered two hours before impact with the Earth’s surface. With a diameter of only 1 meter, it did not pose a threat, and moreover it crashed in a remote and uninhabited area, near the Vatnajokull glacier, in southeastern Island, and according to the data collected it seems to have released an energy equivalent to that of an earthquake of magnitude 4.

Krisztián Sárneczky, the same “asteroid hunter” who had spotted the little 2022 EB 5 shortly before entering our atmosphere and the crash, spotted what was first baptized Sar2594 and then 2022 FD1or another asteroid – always small, that of a refrigerator – only a few hours ahead of yours close passage.


The asteroid 2022 FD1 at 10:13 Italian time on Friday 25 March it passed 8,700 kilometers from the surface of our planet, just touching us, and then continuing its run in the sidereal darkness with a speed of 61,200 km / h. Below you will find an animated reconstruction of his lightning transit over our heads.

On an astronomical scale, even if only by relating the event with less overwhelming dimensions than those of the observable universe, and remaining “in the backyard”, 2022 FD1 has really passed grazing the Earth if we consider that the GPS satellites are located at an average altitude of 20,200 kilometers within Earth’s orbit.

With these numbers 2022 EB5 wins the 13th place in the NASA database which records the objects passed near our planet (without impact, therefore) and classifies them according to the proximity of this passage. Our paths, however, will not cross yet anytime soon: in the next two centuries the orbit predicted for the asteroid should not lead to such close passagesand at the latest in 2032 it could transit 6 million kilometers from Earth.
