(largemeteoroid) perhaps 50–100 metres (150–300 feet) in diameter and having a stony or carbonaceouscomposition. Objects of this size are estimated to collide with Earth once every few hundred years on average (seeimpact event,Earth impact hazard). Because the object exploded in the ...
The Tunguska event is the largest impact event on earth in recorded history. Studies have yielded different estimates of the meteoroid's size, on the order of 60 to 190 metres (200 to 620 feet), depending on whether the body was a comet or a denser asteroid. Since the 1908 event, there...

meteors, meteoroidsminor planets, asteroidsThis letter presents a new solution for the Tunguska event of June 30th, 1908. The solution has been obtained starting from seismic data, is in fair agreement with the observational evidence, and supports the asteroidal hypothesis for the origin of the ...
In and around the tree fall area, the destruction of chums was also more prevalent in directions perpendicular to the meteoroid trajectory, notably along a stretch of the Taimura to the north (Λ, Fig. 3). The pattern of glass damage (red dots in Fig. 3) reflects the behavior of the ...

The resulting simulated radiative flux values are correlated as a function of velocity, altitude, view angle, and meteoroid radius. This correlation is then applied to potential Tunguska entry trajectories to provide a simulated ground heating footprint. Comparing this simulated footprint with the ...
Meteoroid orbits are calculated for a broad family of trajectories with azimuths ranging from 99° (Fast et al , 1976) to 137° (Krinov, 1949) and geocentric velocities ranging from 25 to 40 km/s. Orbits with large azimuth values (120° and larger) are shown to belong to the a...
