What is an Asteroid?

•Large rocky or Metal bodiesrelatively warm inner solar

system

Why chose this topic?

Apophis 99942

History...?

Ancient spirit of evil and destruction..

Demon..

The impact would 100,000 times more powerful than the nuclear bomb dropped on Hiroshima

broke the record for the highest level on the Torino Scale,

diameter is approximately 390 meters (1280 ft).

What is Apophis 99942?

Apophis 99942first discovered by..

June 19,2004.

At first..-received the provisional designation “2004 MN4”

On June 24,2005..-received the permanent number 99942

There are ways to change the track of the asteroid:

• Bump it: a 1-ton Kinetic energy impact

• Thrust it: a ION-Drive rocket engine builds thrust over few weeks on the asteroid

• Tug it: Gravity Tractor

• Nuke it: Nuclear Explosion just above the surface

Kinetic Energy impact - A device that will deflect objects like asteroids and comets by hitting

them with a high-speed spacecraft.. As the material blows away from the object, preventing an impact. Kinetic energy equals the speed of impact squared times mass.

ION Thrust - The ion propulsion system will provide the spacecraft with the thrust that

it will require to reach its target asteroids. Ion propulsion was proved on NASA's Deep Space 1 mission, which tested it and 11 other technologies while journeying to an asteroid and a comet. 

Gravity Tractor - A gravity tractor (GT) is a spacecraft that deflects another object in

space, using only its gravitational field to transmit the required impulse.

Nuclear Explosion - Nuclear explosion plan is the gravity tractor attaching to an asteroid and

firing the craft's engines to push the space rock away using the nuclear missile.

- the solar energy from the sun can actually apply pressure on an object.

- Rocketing packs of ravenous robots out to an asteroid.
