= Jupiter (Callisto) = Jupiter's moon, Callisto﻿ is the best place to hold Championship Igloo Building Competitions because almost all of its giant craters are filled in with ice. The igloos would be very, very sturdy and would never melt!

= MARS =

Mars would be the best place to hold a championship igloo contest because both the north and south poles are covered in ice and snow so it would be really easy to hold the contest all year long!

Uranus



 uranus would be the best to build igloos because the whole planet is cold and is covered in snow and ice.
