How big is that?
3.66 m is 2.1 times an adult man and 14% of a blue whale.
Voyager's dish is the 2nd smallest of the 39 Cosmic Scale objects, and the 39th smallest of the 109 objects across all three SizeItUp games.
Closest in size from the other games: Giant ground sloth (Megatherium) (Prehistoric Giants), 3.5 m tall and Saltwater crocodile (Adult male) (Prehistoric Giants), 5 m long.
