Please note: the results below are estimates based on current (limited) understanding of the impact process and come with large uncertainties; they should be used with caution, particularly in the case of peculiar input parameters. All values are given to three significant figures but this does not reflect the precision of the estimate. For more information about the uncertainty associated with our calculations and a full discussion of this program, please refer to this article

Your Inputs:
- Distance from Impact: 1000.00 meters ( = 3280.00 feet )
- Projectile diameter: 2.00 km ( = 1.24 miles )
- Projectile Density: 3000 kg/m3
- Impact Velocity: 11.20 km per second ( = 6.96 miles per second )
- Impact Angle: 45 degrees
- Target Density: 1000 kg/m3
- Target Type: Liquid water of depth 3.0 km ( = 1.9 miles ), over crystalline rock.
-
Energy:
- Energy before atmospheric entry: 7.88 x 1020 Joules = 1.88 x 105 MegaTons TNT
- The average interval between impacts of this size somewhere on Earth during the last 4 billion years is 1.3 x 106years
-
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 tilt of Earth's axis (< 5 hundreths of a degree).
- The impact does not shift the Earth's orbit noticeably.
-
Crater Dimensions:
- What does this mean?
- The crater opened in the water has a diameter of 24.1 km ( = 15 miles ).
- For the crater formed in the seafloor:
- Transient Crater Diameter:
9.77 km ( = 6.07 miles )
- Transient Crater Depth: 3.46 km ( = 2.15 miles )
- Final Crater Diameter:
13.2 km ( = 8.21 miles )
- Final Crater Depth: 644 meters ( = 2110 feet )
- The crater formed is a complex crater.
- At this impact velocity ( < 12 km/s), little shock melting of the target occurs.
-
Ejecta:
- What does this mean?
- Your position was inside the transient crater and ejected upon impact
