If the 4 billion year old comet 67P/Churyumov-Gerasimenko moving around the sun in the Kuiper belt close to Jupiter, (orbital period around the sun of 6.45 years and max velocity of 38km/sec), on which the unmanned lander PHILAE from the orbiting ESA spacecraft Rosetta has landed after a10 year journey in interplanetary space, were to fall in New York city, the pic shows how the NYC skyscrapers would be dwarfed by 67P.
European Space Agency (ESA) deserves full credit for getting an unmanned spacecraft to land for the first time on a comet, which had no activity for the past 4 billion years ie. 4,000,000,000 years !! (in comparison earth is 11,000,000,000 years old and bronze/metal age started just 8000 years back)..
Wow ..... getting goosebumps on my body !
