Much of the water on both planets is also thought to have come from impacts from comets, icy bodies formed in the outer solar system.In fact, water probably once dominated the Venusian atmosphere. Venus and Earth are similar in size and mass, so Venusian volcanoes may well have outgassed ...
Ice giants are massive planets composed mainly of substances that are heavier than helium and hydrogen. The ice giants, Uranus and Neptune, are primarily made up of oxygen, nitrogen, carbon, and sulfur – the next most abundant elements in the Sun after hydrogen and helium. ...
