How big is the Churyumov-Gerasimenko comet

With a nucleus size of 3.5×4 km, 67P/Churyumov–Gerasimenko seems like a mere speck. But Michel (@quark1972 on Twitter) shows what the comet would look like if it were gently set down in Los Angeles. I wish the city would commission a life-size replica as public art!
