Graphic shows the immense size of Rosetta’s comet and risks such large objects pose to Earth

Comet 67P/Churyumov-Gerasimenko, just 3km wide, would vaporize Los Angeles if the comet impacted the city. However, this graphic was produced to show the comet’s size. Churyumov-Gerasimenko doesn’t cross Earth’s orbit and there is no chance of a near-Earth collision.
August 2014SPACEOur sense of scale tends to adjust to circumstances. So when we think about comets it is easy to compare them with other astronomical objects. In which case comet 67P/Churyumov-Gerasimenko, just 3km wide, sounds tiny. However, as you can see in the image above, things look rather different when you compare the comet to something we are really familiar with – such as tall buildings. While Churyumov-Gerasimenko is small enough that one could walk from one end to the other fairly in less than an hour, it’s easy to forget the three dimensional nature of something like this – 3km across is no big deal, but two kilometers helps make sense of what happened to the dinosaurs. The image is by @quark1972, who combined a photograph of Los Angeles with an image from the Rosetta spacecraft rendezvousing with Churyumov-Gerasimenko, prior to going into orbit and eventually landing.
While Rosetta will be doing its best to touch down very gently on the comet’s surface, we can’t count on Churyumov-Gerasimenko doing the same if it ever paid LA a visit. You can get some idea of what would happen in such a collision here, although the scale of the damage depends greatly on the impact speed you choose to enter. Since Churyumov-Gerasimenko never crosses the Earth’s orbit there is no danger of a collision, at least until a close encounter with some other planet shifts its orbit. Unfortunately the same cannot be said for other, even larger, asteroids and comets. –IFLScience

    Wow……..bad day not only for LA, but for the planet

    Oh, come on Dudes: rocks falling from OUTER SPACE? What’s next? Rocks that float? Viral outbreaks caused by pigs? By chickens? Come on! I ain’t the sharpest bowling ball, maybe, but I ain’t stoopid. . . .

    If something that size was to impact, it would wipe on not just Los Angeles but all of Nth and South USA and send tidal waves over all the islands including NZ and over the coastal regions of Australia, PNG, it would literally annihilate half the world at least. A house size would knock out Los Angeles. God forbid this ever happening.

    The dinosaurs were wiped out in the great flood of Noah’s days, all the archaeological evidence proves this. There were some of each land animal on the Ark also so there would have been dino’s on board, but after the earths canopy was gone they couldn’t have survived the harsh conditions which we have today. Before the flood the earth was a tropical paradise from one end to the other, again the archaeological evidence points to this fact. Just saying. Have a nice day. 🙂

    I think this graphic is an interesting graphic and nothing else. So many people really have no concept on what a comet is. They see it as a fuzzy snowball or a large object with a bright tail streaking across the sky. To see what this one looks like compared to one of our cities is fascinating.

    Looks like a big boot stomping on LA.
