Asteroida minęła Ziemię (mixfilez)
Your Inputs: Distance from Impact: 100.00 km = 62.10 miles Projectile Diameter: 27.00 m = 88.56 ft = 0.02 miles Projectile Density: 3000 kg/m3 Impact Velocity: 17.00 km/s = 10.56 miles/s Impact Angle: 45 degrees Target Density: 2500 kg/m3 Target Type: Sedimentary Rock Energy: Energy before atmospheric entry: 4.47 x 1015 Joules = 1.07 MegaTons TNT The average interval between impacts of this size somewhere on Earth is 115.7 years Atmospheric Entry: The projectile begins to breakup at an altitude of 54000 meters = 177000 ft The projectile bursts into a cloud of fragments at an altitude of 16600 meters = 54500 ft The residual velocity of the projectile fragments after the burst is 9.19 km/s = 5.71 miles/s The energy of the airburst is 3.16 x 1015 Joules = 0.76 x 100 MegaTons. No crater is formed, although large fragments may strike the surface. Major Global Changes: The Earth is not strongly disturbed by the impact and loses negligible mass. The impact does not make a noticeable change in the Earth’s rotation period or the tilt of its axis. The impact does not shift the Earth’s orbit noticeably.
