Il sito che calcola l'effetto dell'impatto di un asteroide

provate a mettere un po' di dati a caso....

io ne ho messi alcuni abbastanza "pesi" e mi è venuto questo:

Major Global Changes:
The Earth is completely disrupted by the impact and its debris forms a new asteroid belt orbiting the sun between Venus and Mars.

eh infatti
ora l'ho messo

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...

avessi detto diametro di 10 metri mi sarei meravigliato

E' quel "basta" che mi fa impazzire.

: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. 

Mi sembra che non succedano poi tutti sti macelli

Uttio peggio di un combat report di oGame

Distance from Impact: 15000.00 km = 9315.00 miles
Projectile Diameter: 200000.00 m = 656000.00 ft = 124.20 miles
Projectile Density: 160000 kg/m3
Impact Velocity: 51.00 km/s = 31.67 miles/s (Your chosen velocity is higher than the maximum for an object orbiting the sun)
Impact Angle: 90 degrees
Target Density: 2500 kg/m3
Target Type: Sedimentary Rock

...

The Earth is strongly disturbed by the impact, but loses little mass.
56.68 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.

Transient Crater Diameter: 11900 km = 7370 miles
Transient Crater Depth: 4190 km = 2610 miles

Thermal Radiation:

Time for maximum radiation: 180 seconds after impact

Your position is inside the fireball.
The fireball appears 1080 times larger than the sun
Thermal Exposure: 1.24 x 1014 Joules/m2
Duration of Irradiation: 1.07e+06 seconds
Radiant flux (relative to the sun): 116000

Effects of Thermal Radiation:

Clothing ignites
Much of the body suffers third degree burns
Newspaper ignites
Plywood flames
Deciduous trees ignite
Grass ignites

Seismic Effects:

The major seismic shaking will arrive at approximately 3000 seconds.
Richter Scale Magnitude: 15.5 (This is greater than any earthquake in recorded history)
Mercalli Scale Intensity at a distance of 15000 km:

X. Most masonry and frame structures destroyed with their foundations. Some well-built wooden structures and bridges destroyed. Serious damage to dams, dikes, embankments. Large landslides. Water thrown on banks of canals, rivers, lakes, etc. Sand and mud shifted horizontally on beaches and flat land. Rails bent slightly.
XI. As X. Rails bent greatly. Underground pipelines completely out of service.

Ejecta:

Your position is in the region which collapses into the final crater.

Air Blast:

The air blast will arrive at approximately 45500 seconds.
Peak Overpressure: 4.44e+08 Pa = 4440 bars = 63100 psi
Max wind velocity: 17000 m/s = 38000 mph
Sound Intensity: 173 dB (Dangerously Loud)
Damage Description:

Multistory wall-bearing buildings will collapse.
Wood frame buildings will almost completely collapse.
Multistory steel-framed office-type buildings will suffer extreme frame distortion, incipient collapse.
Highway truss bridges will collapse.
Highway girder bridges will collapse.
Glass windows will shatter.
Cars and trucks will be largely displaced and grossly distorted and will require rebuilding before use.
Up to 90 percent of trees blown down; remainder stripped of branches and leaves.
