Quote:'Planet killer' asteroid found hiding in sun's glare

'It's estimated at 1.5km wide - nearly a mile - a size that astronomers class as "planet killers" due to the damage they
can cause. The rock is believed to be in the top 5% of largest-known PHAs.
Called 2022 AP7, it's one of several newly discovered asteroids found orbiting near Earth and Venus.

Archived Sky News:
Most likely scenario in terms of probability:

Distance from Impact:  1600.00 km ( = 994.00 miles )
Projectile diameter:  1.50 km ( = 0.93 miles )
Projectile Density:  5000 kg/m3
Impact Velocity:  17.00 km per second ( = 10.60 miles per second )
Impact Angle:  45 degrees
Target Density:  1000 kg/m3
Target Type: Liquid water of depth 3.7 km ( = 2.3 miles ), over crystalline rock.

Final Crater Diameter: 15.4 km ( = 9.57 miles )
Final Crater Depth:  674 meters ( = 2210 feet )

Air Blast:
The air blast will arrive approximately 1.35 hours after impact.
Damage Description: Glass windows may shatter.

Tsunami Wave:
The impact-generated tsunami wave arrives approximately 2.4 hours after impact. 
Tsunami wave amplitude is between:  23.9 cm ( = 9.4 inches) and 32.9 meters ( = 108.0 feet).

-vs-

You're about to have a bad day!!

Distance from Impact:  160.00 km ( = 99.40 miles )
Target Type: Sedimentary Rock

Final Crater Diameter: 25 km ( = 15.5 miles )
Final Crater Depth:  780 meters ( = 2560 feet )

Thermal Radiation:
Time for maximum radiation:  1.28 seconds after impact
Visible fireball radius:  19.7 km ( = 12.2 miles ) The fireball appears 27.9 times larger than the sun
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:
Damage negligible in buildings of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built or badly designed structures; some chimneys broken.

Ejecta:
The ejecta will arrive approximately 3.06 minutes after the impact.
At your position there is a fine dusting of ejecta with occasional larger fragments
Average Ejecta Thickness:  19 cm ( = 7.5 inches )
Mean Fragment Diameter:  4.67 cm ( = 1.84 inches ) 

Air Blast:
The air blast will arrive approximately 8.08 minutes after impact.
Max wind velocity:  188 m/s = 420 mph
Sound Intensity:  101 dB (May cause ear pain)
Damage Description:
Multistory wall-bearing buildings will collapse.
Wood frame buildings will almost completely collapse.
Highway truss bridges will suffer substantial distortion of bracing.
Glass windows will shatter.
Up to 90 percent of trees blown down; remainder stripped of branches and leaves.
