Earth's last chance is in hand of ChinaEarth’s last chance99942 Apophis is a well known name to astronomers and scientists. If you are not then know that this is a word that made scientists a little bit worried around 2004. This is an asteroid which has a small probability (up to 2.7%) that it would strike theEarthin 2029.Additional observation predicted that this asteroid is not going to smash with our planet or our dear moon. But it will cross through a gravitational keyhole which can cause this rock to divert from its original path and force it to crash into our planet.But, a recent research in Tsinghua University, Beijing, China, reveals a project call Kamikaze (from Kami - "god" and kaze - "wind”).It is a satellite that will smash a soler sail into Apophasis and divert its path away from the gravitational keyhole.Earth's last chance is in hand of ChinaBy analysing the trajectory, speed and impact of a spacecraft, Gong says, “The results show that a 10 kg solar sail with a lead-time of one year can move Apophis out of a 600-m keyhole area in 2029.” The craft would also be sent into a retrograde orbit of the Earth to build up speed, so it will be moving at a super fast 90km/s by the time it collides with the asteroid.Europina space agency is also thinking about smashing a rocket into Apophasis.
