(2003), to invert for the trajectory parameters: the meteor penetrates linearly through the atmosphere with a constant velocity, and the shockwave speed of
320 m/s
is uniform in the atmosphere.
How fast can a asteroid travel?
Asteroids, the most common type of impactor, slam into the Earth at an average velocity of
18 km/s
. Short-period comet impacts with the Earth are less common, but have higher impact velocities averaging 30 km/s.
Can a shockwave travel around the world?
As far as we known, geologists,etc,
its not impossible, but very very unlikely unless we are looking at an extinction type vent
.
How fast would an asteroid impact affect Earth?
Due to Earth’s escape velocity, the minimum impact velocity is 11 km/s with asteroid impacts averaging around
17 km/s
on the Earth. The most probable impact angle is 45 degrees. Impact conditions such as asteroid size and speed, but also density and impact angle determine the kinetic energy released in an impact event.
Can a shock wave travel faster than the speed of sound?
In particular,
shock waves travel faster than sound
, and their speed increases as the amplitude is raised; but the intensity of a shock wave also decreases faster than does that of a sound wave, because some of the energy of the shock wave is expended to heat the medium in which it travels.
Is shock wave lithotripsy painful?
Shock wave lithotripsy is a safe treatment to get rid of kidney stones.
Passing even tiny kidney stone fragments can hurt — sometimes a lot
. If you have shock wave lithotripsy, expect to feel some discomfort as stone fragments pass in the days and weeks after treatment.
How fast was the asteroid that killed the dinosaurs?
Scientists calculate that it was blasted into Earth by a 10-kilometer-wide asteroid or comet traveling
30 kilometers per second
— 150 times faster than a jet airliner. Scientists have concluded that the impact that created this crater occurred 65 million years ago.
How fast do spaceships travel?
This really depends on what you mean by “into space.” If you just want to get into orbit around the Earth, you need to reach speeds of at least
4.9 miles per second
, or about 17,600 miles per hour.
What is the fastest moving asteroid?
The asteroid, named 2021PH27, finishes its orbit around the sun in just
113 days
, which is faster than any other asteroid in our solar system. Using the Dark Energy Camera (DECam) based in Chile, astronomers have discovered the fastest asteroid in our solar system.
Would you feel a shockwave in space?
A ‘shock wave’ is the disturbance of material that’s created when a wave moves through a medium at greater than the local speed of sound. Provided there is a ‘medium’ of sufficient density through which a shock wave can travel,
there is no reason why shock waves can’t form in space
.
Can you feel explosions in space?
What is the difference between a blast wave and a shock wave?
A blast wave travels faster than the speed of sound and the passage of the shock wave usually lasts only a few milliseconds
.
What would happen if the moon was hit by an asteroid?
The Moon is very big, and any small object hitting it would have very little effect on its motion around the Earth, because the Moon’s own momentum would overwhelm that of the impact.
Most asteroid collisions would result in large craters and little else
; even the largest asteroid known, Ceres, wouldn’t budge the Moon.
How much damage would a 1 mile wide asteroid do?
If a mile-wide asteroid hit Earth, it would strike the planet’s surface at about
30,000 miles per hour
(48,280 kilometers per hour). An asteroid that big traveling at that speed has the energy roughly equal to a 1 million megaton bomb. It’s difficult to imagine 1 million megatons, so let’s try some smaller sizes.
What asteroid will hit Earth?
| Model of 99942 Apophis’s shape, assuming the entire surface is of a similar composition. | Discovery | Discovered by Roy A. Tucker David J. Tholen Fabrizio Bernardi |

How strong is a shockwave?
Close to an explosion, a shock wave can travel at several times the speed of sound and reach pressures of ten or more atmospheres
, producing devastating effects.
How far can a shockwave travel?
Within a
6-km (3.7-mile) radius of a 1-megaton bomb
, blast waves would produce 180 metric tons of force on the walls of all two-story buildings, and wind speeds of 255 km/h (158 mph). In a 1-km (0.6-mile) radius, the peak pressure is four times that amount, and wind speeds can reach 756 km/h (470 mph).
How fast do explosions travel?
Gas explosions can either deflagrate or detonate based on confinement; detonation velocities are generally around
1600 m/s to 1800 m/s but can be as high as 3000 m/s
. Solid explosives often have detonation velocities ranging beyond 4000 m/s to 10300 m/s. Detonation velocity can be measured by the Dautriche method.
Are you put to sleep for lithotripsy?
Some people have lithotripsy under local anesthesia, which numbs the area to prevent pain. However,
most people have the procedure under general anesthesia, which puts them to sleep during the procedure
.
Is a stent required after lithotripsy?
Conclusion: Routine placement of a ureteral stent is
not mandatory
in patients without complications after ureteroscopic lithotripsy for impacted ureteral stones.
Why is there blood in urine after lithotripsy?
Your Recovery
This treatment uses sound waves to break kidney stones
into tiny pieces. These pieces can then pass out of the body in the urine. You may have a small amount of blood in your urine after this treatment. Your urine may be slightly pink or reddish.
How big of an asteroid would it take to destroy the Earth?
Ultimately, scientists estimate that an asteroid would have to be about
96 km (60 miles) wide
to completely and utterly wipe out life on our planet.
Where did the asteroid hit 65 million years ago?
Sixty-six million years ago, a mountain-size asteroid slammed into Earth
just off the coast of Mexico’s Yucatán Peninsula
, dooming the dinosaurs and leading to their extinction.
What happened when the asteroid hit Earth 65 million years ago?
What Happened in Brief. According to abundant geological evidence, an asteroid roughly 10 km (6 miles) across hit Earth about 65 million years ago. This impact made
a huge explosion and a crater about 180 km (roughly 110 miles) across
.
What is the fastest speed that man has traveled?
Fastest human spaceflight
The crew of NASA’s Apollo 10 moon mission reached a top speed of
24,791 mph
(39,897 kph) relative to Earth as they rocketed back to our planet on May 26, 1969. That’s the fastest any human beings have ever traveled.
How fast can a human go without dying?
This is a well documented field, and the average maximum survivable g-force is about
16g (157m/s) sustained for 1 minute
. However this limit depends on the individual, whether the acceleration is applied to one’s entire body or just individual parts and the time in which the acceleration is endured over.
What is the fastest speed in space?
But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than
300,000 kilometers per second
(186,000 miles per second).
