SCOPOLIA Suppl. 6 - 2013 
Mežakelski meteorit spada v skupino kamnitih meteoritov hondritov. Ljubiteljski astronomi Jure Atanackov, Javor Kac in Gregor Kladnik so izračunali, da je imel meteorit ob vstopu v atmosfero okoli 300 kilogramov in za meteorite razmeroma nizko hitrost 14 km/sekundo. Za en obhod okoli Sonca je potreboval 3,4 leta. Izračunali so njegovo orbito; torej pot okoli Sonca, po kateri je potoval. Mežakelski meteorit je s tem postal šele 11. meteorit z znano orbito, kar ga uvršča v sam vrh svetovne dediščine. 
Summary 
On April 9th 2009, a few seconds before 3 o'clock in the morning, a frightening roar was heard by some inhabitants of the Austrian Carinthia and the Upper Sava Valley in Slovenia. The firefighters who were at that time attending a fire at Pejce, saw a very bright and unusually long shooting star, which eventually disappeared above Mt Mežakla in direction of Blejska Dobrava. Astronomical and all-sky cameras detected this celestial phenomenon as a very bright object, and it was immediately clear to astronomers that a meteorite had just fallen there. 
On May 17th 2009, Jožef Pretnar and Bojana Krajnc from Gorje were hiking towards Planinski vrh on Mežakla Mt. They found a stone, which was different than any others they knew, and Jožef was convinced that this was a meteorite. And indeed it was. After 101 years, when a meteorite hit the ground near the village of Avče, this was only the second meteorite that fell on Slovenian territory. Bojana and Jožef named it BOJO. In the impact hole, it was shattered in several pieces with a total mass of 2.293 kilograms. The second fragment of the same meteorite with the mass of 361 grams were recovered by Ralph Sporn and Martin Neuhofer on June 21st 2009, while the third fragment and at the same time the largest piece of the meteorite was found by Danijel Repe. Its mass was 956.4 grams and did not disintegrate upon its impact. 
The Mežakla meteorite belongs to the group of stone meteorites known as chondrites. Amateur astronomers Jure Atanackov, Javor Kac and Gregor Kladnik calculated that during its entry into the atmosphere the meteorite weighed about 300 kilograms and had relatively low (for meteorites) speed at 14 km/second. For one circling of the Sun it needed 3.4 years. In this way, its orbit was calculated, i.e. the path around the Sun along which it travelled. The Mežakla meteorite thus became only the 11th meteorite with accurately determined orbit, which puts it at the very top of world heritage.
