According to the University of Huelva, it was undoubtedly the result of a rock crashing into the lunar surface. J. M. Madiedo saw the footage of the strike once the telescope´s software had processed the impact. The flash produced

The best estimate for the mass of the object is accepted to be around 10.000 tons. The object entered our atmosphere at an incredible speed of 19 km/s releasing about 500 kilotons of energy. It is classified as an ordinary chondrite of the type LL5. After the explosion most of the object became dust. Only small fragments made it to the ground. First studies of material samples found suggest the age of

Collision in our planetary system: it started with an event on Jupiter

Feb 11

The direct observation of impacts in our planetary system started in 1994 when astronomers could directly observe the impacts of cometary fragments on Jupiter: the newly discovered comet Shoemaker-Levi was caught by the large gravitational field of Jupiter. First its orbit was changed. Later Jupiter´s gravitational forces became larger than the inner stability of the comet which resulted in a break-up of the comet. Since that a planetary pearl necklace approach Jupiter
