According to wikipedia:
"Despite the vast size of its coma, Halley's nucleus is relatively small: barely 15 kilometres (9.3 mi) long, 8 kilometres (5.0 mi) wide and perhaps 8 kilometres (5.0 mi) thick."
"Mount Everest's elevation of 29,032 feet (8,849 metres) and is the highest mountain in the world."
If the coming comet is larger than Everest, it'll be a little more than half the size of Halley so maybe... just maybe...
