Size Comparison: Jupiter vs Uranus

Size comparison between the two gas planets Jupiter and Uranus. Jupiter is almost 3 times larger than Uranus, its gravity is 2.5 times higher. Uranus is 4 times farther from the sun than Jupiter; it has three times fewer natural satellites but has a good number, however, with some moons reaching 1500 km in diameter (Titania and Oberon).

We notice that the two planets have a fairly similar atmospheric composition. The cyan color of the planet Uranus is due to Methane, if we could smell this planet, then it would have a strong smell of cow dung. While the brown and orange colors of Jupiter are due to mixtures of sulfur, phosphorus or possibly hydrocarbons.

Note: if one of the objects is not visible, it just means that it is too tiny to be displayed compared to the other one.
