The real size of Jörmungandr
Jörmungandr (aka World Serpent) is said to encircle the Earth which has a circumference of about 40,075 km (24,901 mi). So, that would be his length. I looked up average length to circumference ratio of snakes which for vipers averages about to 6.So, Jörmungandr‘s circumference would be about one-sixth of his length which comes to be around 6,679.16 km (4,150.24 mi). This implies that his body has a diameter of 2126.04 km (1,321.06 mi). For comparison, that is the approximately half the distance between Australia and New Zealand.
He would probably look like this as seen from space.
Also, about half of his body would lie in the exosphere.
