How big does an object have to be to destroy?
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.
What speed can destroy the earth?
We’d use a particularly powerful model — big enough to hit escape velocity of 6.8 miles per second (11 kilometers per second) even after atmospheric considerations — and launch it all into the sun or randomly into space.
What happens if a coin hits the earth at light speed?
If you give it a push such that it reaches the speed of light you’ll break physics. The penny would melt and break apart from friction before it reached the earth. If it somehow did reach the earths atmosphere intact, it would still be destroyed before reaching the surface.
What would happen if an object Travelling at the speed of light hit the earth?
It wouldn’t annihilate the earth completely, but it would wipe out everything on the surface of our planet, leaving it a glowing rock with a surface temperature of about 5,000–6,000º C, or a bit hotter than the surface of the sun.
What size asteroid would destroy a city?
Asteroids larger than approximately 35 meters across can pose a threat to a town or city. However the diameter of most small asteroids is not well determined, as it is usually only estimated based on their brightness and distance, rather than directly measured, e.g. from radar observations.
Will the sun destroy Earth?
As the Sun evolves over time, it will heat up and increase its rate of nuclear fusion, eventually outputting so much energy that Earth’s oceans will boil. After 1 or 2 billion more years, this will likely sterilize life on our planet entirely.
What planet blew up?
Our solar system is an active place. Flash! An asteroid or icy object collided with the gas giant Jupiter on Sept. 13, where it eventually blew up in the planet’s thick clouds.
What would happen if a small rock hit the Earth at the speed of light?

What are the physical consequences of traveling at the speed of light?
Firstly, the physical consequence of traveling at the speed of light is that your mass becomes infinite and you slow down. According to relativity, the faster you move, the more mass you have. The same works on Earth when you’re driving down the freeway.
What would happen if an object with non-zero mass hits Earth?
If any object with a non zero rest mass, even as small as a needle, hits the earth at the speed of light in a vacuum, the laws of physics will have been broken and causality and the universe will cease to exist. How do i know this: I don’t.
What is the speed of the Earth’s gravity?
The mass of our planet is an immense 5.9 x 10^24 kg. The needle is moving at the speed of light, or around 300,000,000 m/s. The Earth is moving at a much lower speed, 30,000 m/s. And if you use conservation of momentum, you will find that there is literally no reaction between the two.
What would happen if a needle hits the Earth at speed?
Everyone dies. If any object with a non zero rest mass, even as small as a needle, hits the earth at the speed of light in a vacuum, the laws of physics will have been broken and causality and the universe will cease to exist. How do i know this: I don’t.
