It is 2156 . In this year scientist of NASA discovered something horrifying. That is an astroid is coming forward to earth. If it collapse with earth then our earth will not live no long. That astroid is very large in size that is about a size of mount Everest.That size is enough to destroy our home planet. Scientist calculated that this Astroid will collapse with earth 2157 in 7th February. Scientist also calculated that there is no chance to escape from that mega Astroid. Then all the country's people get too much disappointed because of that bad news. Every where people trying something to escape from that Astroid but alas! there was no chance. Then NASA dicided to do something . Finally they find another planet like earth and that was about 405 light years from earth . scientist calculated that to reach that planet it will take 178 years and coming back will take another 178 years . That's mean NASA failed here to do that mission....
