basta una palla di ghiaccio di 10 km di diametro (una cometa) a velocità minima (17 Km/s) e che cada in mare per provocare danni terrificanti... [/supersaibal]
:master: fino a 1000 km di diametro ho sempre la stessa cosa

Your Inputs:
Distance from Impact: 1000.00 km = 621.00 miles
Projectile Diameter: 1000000.00 m = 3280000.00 ft = 621.00 miles
Projectile Density: 8000 kg/m3
Impact Velocity: 72.00 km/s = 44.71 miles/s
Impact Angle: 45 degrees
Target Density: 1000 kg/m3
Target Type: Liquid Water of depth 1000.00 meters, over typical rock.
Energy:
Energy before atmospheric entry: 1.09 x 1031 Joules = 2.59 x 1015 MegaTons TNT
The average interval between impacts of this size is longer than the Earth's age.
Such impacts could only occur during the accumulation of the Earth, between 4.5 and 4 billion years ago.
Major Global Changes:
The Earth is not strongly disturbed by the impact and loses negligible mass.
6.21 percent of the Earth is melted
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.
