On which planet, except the Earth, is the greenhouse effect observed?

Saturn

Jupiter

Uranium

Venus

If a planet's atmosphere contains radiatively active gases, they will radiate energy in all directions. Part of this radiation is directed towards the surface, warming it. The greenhouse effect on Venus is particularly large because its dense atmosphere consists mainly of carbon dioxide.
