Il cielo in Russia, nella regione Lipetsk, è stato illuminato in pieno giorno da una palla di fuoco, causata dall'esplosione nell'atmosfera di un piccolo asteroide.
Nonostante le sue dimensioni ridotte, con un diametro attorno ai 4 metri, la sua esplosione ha rilasciato un'energia di 2,8 chilotoni, circa un sesto della potenza della bomba atomica sganciata su Hiroshima.
Lo scoppio, immortalato da alcuni passanti, non ha però causato danni o feriti.
