Ou puis-je avoir le rapport entre le diamètre d´une météorite et ces conséquences si elle s´écrasait sur terre? (taille du cratère, conséquences sur l´environnement).

Par ex que ce passerait-il avec une météorite d´un diamètre de 50 mètres? (dans un rayon de combien de km on en subit les effets, etc...)

merci

J´ai trouver ça pour calculer toi même.
J´ai rien trouver d´autre dsl...

Voila ce que j´ais essayé :

Your Inputs:
Distance from Impact: 2.00 km = 1.24 miles
Projectile Diameter: 120000.00 m = 393600.00 ft = 74.52 miles
Projectile Density: 3 kg/m3
Impact Velocity: 200000.00 km/s = 124200.00 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

Energy:
Energy before atmospheric entry: NaN x 10NaN Joules = 1.30 x 1016 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.
41.07 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.

Crater Dimensions:
What does this mean?

Transient Crater Diameter: 3030 km = 1880 miles
Transient Crater Depth: 1070 km = 665 miles

Final Crater Diameter: 8630 km = 5360 miles
Final Crater Depth: 4.53 km = 2.81 miles

The final crater is replaced by a large, circular melt province.
At this impact velocity ( < 12 km/s), little shock melting of the target occurs.
Melt volume = 124 times the crater volume
At this size, the crater forms in its own melt pool.

J´éspère qu´on sera jamais frappé par un météorite de 120km de diamètres, de densité 3, de vitesse 200 000 km/s ( ) et d´angle d´incidence 90°

truc de fou qui me ferait presque douter de l´inexistance de Dieu puisqu´avec ces caractéristiques là je doute fortement au hasard...

c´est sur moi je douterai tout simplement de mon futur proche

C´est dingue tout sa.

Your Inputs:
Distance from Impact: 5000.00 km = 3105.00 miles
Projectile Diameter: 500000.00 m = 1640000.00 ft = 310.50 miles
Projectile Density: 1500 kg/m3
Impact Velocity: 100000.00 km/s = 62100.00 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

Energy:
Energy before atmospheric entry: NaN x 10NaN Joules = 1.17 x 1020 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 completely disrupted by the impact and its debris forms a new asteroid belt orbiting the sun between Venus and Mars.

Oui, d´accord, je reve
