Because during their formation Uranus and Neptune incorporated their material as either ice or gas trapped in water ice, the term ice giant came into use. [ 2 ] [ 4 ] In the early 1970s, the terminology became popular in the science fiction community, e.g., Bova (1971), [ 5 ] but the earliest scientific usage of the terminology was likely by ...
Ice from a theorized superionic water may possess two crystalline structures. At pressures in excess of 50 GPa (7,300,000 psi) such superionic ice would take on a body-centered cubic structure. However, at pressures in excess of 100 GPa (15,000,000 psi) the structure may shift to a more stable face-centered cubic lattice.
TW Hydrae b is an ice giant, an exoplanet with a radius and mass close to that of the ice giants Neptune and Uranus. It may have an equilibrium temperature of around 40 K (−233.2 °C; −387.7 °F). It has an estimated mass of around 22.72 M E (or 1.5 M Neptune) and a possible radius of 4.25 R 🜨.
Neptune's more varied weather when compared to Uranus is due in part to its higher internal heating. The upper regions of Neptune's troposphere reach a low temperature of 51.8 K (−221.3 °C). At a depth where the atmospheric pressure equals 1 bar (100 kPa), the temperature is 72.00 K (−201.15 °C). [128]
Although the exact temperature can be hard to control, the weight ratio of salt to ice influences the temperature: −10 °C can be achieved with a 1:2.5 mass ratio of calcium chloride hemihydrate to ice. −20 °C can be achieved with a 1:3 mass ratio of sodium chloride to ice. [citation needed]
Mars, Jupiter, Uranus, Neptune, Venus and Saturn will align in the sky on Jan. 21, resulting in both astronomical and astrological significance in the cosmos January's Rare Planet Parade Will Have ...
Neptune's orbit is also nearly circular, with a low eccentricity of 0.0097; [15] as such, each season on Triton lasts roughly 40 years, and Triton's seasonal variations are almost entirely governed by the tilt of its rotational axis relative to the Sun. [16] [a] Triton is tidally locked, with one hemisphere facing Neptune at all times; Triton's ...
