Novootkriveni 50-metarski asteroid odmah došao na

The asteroid in question, 2023 DW, registers as a 1 on the Torino scale; that is, it's not dangerous.

It's probably between 1/5 of and 1/160 of the mass of Dimorphos, which was successfully deflected by a NASA probe last year. Since its largest dimension is 47 meters, Dimorphos's smallest dimension is 116 meters, and Dimorphos's largest dimension is 177 meters:

    (((47 / 116) ^ 3) ^ -1) * (1/3) ≈ 5.01140081356; assumes 2023 DW is 3x the density of Dimorphos

    (((47 / 177) ^ 3) ^ -1) * (3/1) ≈ 160.231345656; assumes 2023 DW is 1/3 the density of Dimorphos

Either way, it'd be too small to pose a hazard even if it was on a trajectory to hit the Earth, because NASA has shown it's able to deflect larger objects before. They'd have about a decade to basically build a copy of DART and throw it at 2023 DW.

Even if it hit, 2.15E8 kg (0.2x Dimorphos mass) at 30 km/s is 7.74E17 joules, or about 185 megatons of TNT. It'd basically be a truly gigantic strategic nuke aimed at random part of the planet; humanity has indeed built nuclear weapons with about 1/3 the power and set them off. And it'd be less than 7.74E17 joules, because 2023 DW is less massive than 2.15E8 kg, the atmosphere would slow it down, and it likely wouldn't come in at as high a speed as 30 km/s anyway.

Ybte kako su se samo odjednom poceli pojavljivati i svaki prijeti Zemlji, di su prije bili?
