Uranus and its neighbour Neptune, the next planet outward from the Sun, are nearly twins in size. Measured at the level of the atmosphere at which the pressure is one bar (equivalent to Earth’s sea-level pressure), Uranus’s equatorial radius of 25,559 km (15,882 miles) is 3.2 percen...

Uranus hits the coldest temperatures of any planet. With minimum atmospheric temperature of -224°C Uranus is nearly coldest planet in the solar system. While Neptune doesn’t get as cold as Uranus it is on average colder. The upper atmosphere of Uranus is covered by a methane haze which hi...

Many of the satellites of the gas-giant planets have bulk densities indicating that their interiors are mixtures of silicate rocks and theiceof common volatiles, mainly water. On some of these bodies (e.g.Jupiter's satellitesGanymedeandEuropa, Uranus's satelliteAriel,Neptune's satelliteTriton, an...
In all, at least27 moonscircle Uranus, with the four largest ranging from Ariel, at 720 miles (1,160 kilometers) across, to Titania, which is 980 miles (1,580 kilometers) across. Scientists have long thought that Titania, given its size, would be most likely to retain internal heat, ...
Size comparison of all the Solar Systems moons. Credit: NASA/The Planetary Society With an average orbital speed of 6.66 km/s, Miranda takes 1.4 days to complete a single orbit of Uranus. Its orbital period (also 34 hours) is synchronous with its rotational period, meaning that it is tidal...
Despite being almost a billion miles (about 1.6 billion km) closer to the sun than Neptune, Uranus is colder in some places. It holds the record for the coldest temperature ever measured in the solar system for a planet: -371 °F (-224 °C) or just 49 °K. On average, Pluto’s ...
On the other hand,Neptunekeeps an average distance of 4.5 billion kilometers (2.8 billion mi) from the Sun and so stays in heated contention for the coldest planet. Which planet do you think is the coldest—Neptune, with an average temperature of -214 degrees Celsius (-353.2 °F), or U...
