Past Plans
Stopping Asteroids from Hitting Earth
Killer Asteroids whipping out All life forms ?
There have been many past plans on stopping asteroids from hitting us. Do you ever wonder what they are ? How do people come up with these? Well this flyer is going to give you the information you need.
No Explosions
Stopping an asteroid without any explosions ; how is that possible ? A french scientist came up with the idea of knocking the asteroid of its orbit. This is possible by blocking the suns radiation from reaching the asteroid which will eliminate the Yarkovsky effect. Yarkovsky effect is a phenomena which produces a tiny amount of thrust on the warm side of an asteroid. Eliminating this effect will knock the asteroids orbit slightly which would make a big change on it's route. How will we block the suns radiation ? A group of flying space crafts could get in between the sun and asteroid thus blocking the suns radiation.
A Mining Device
Building a mining device to stop an asteroid might sound bizarre until you hear the full story. Well the mining device would dig a hole into the asteroid and eject the device at high speed which would eject the asteroids own innards to hit the asteroid. Which would slowly push the asteroid away from its orbit and also decrease it mass.
Explosions
There are so many explosives devices which can be put to a good use. We can place the explosives surrounding around the asteroid. The explosives should be far enough that it would not damage the asteroid but would have enough energy to create a force strong enough to steer the asteroid away.
PAINT ?
Can we stop a killer asteroid with a lot of paint ? This theory seems a bit crazy but it is possible. The theory also eliminates the Yarkovshy effect like the first theory which was mentioned . But this works in a completely different way . The sun warms one of the asteroids side, this side emits more thermal radiation which very slightly moves the asteroid. Blocking some the areas with paint would eliminate this pattern and alternate the asteroid path.
Will they save us ?
All these ideas may or may not work but they are indeed great ideas which would help us save our planet in case of an asteroid. None of these ideas have actual been put to test but if they were we would be saved from getting hitting by a killer asteroid.
