Jun 5, 2023 · Uranus is blue-green in color, as a result of the methane in its mostly hydrogen-helium atmosphere. The planet is often dubbed an ice giant, since at least 80% of its mass is a fluid mix of water...
methane hydrate. Uranus is the seventh planet from the Sun. It is a gaseous cyan -coloured ice giant. Most of the planet is made of water, ammonia, and methane in a supercritical phase of matter, which astronomy calls "ice" or volatiles.
Neptune is the eighth and farthest known planet from the Sun. It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth and slightly more massive, but denser and smaller, than fellow ice giant Uranus.
Sep 21, 2023 · Mars may escape the Sun’s actual reach — it’s at the borderline — but that water will likely all be gone by the time the red giant star takes over the inner solar system. The gas giant...
- The Birth of the Sun: According to Nebular Theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust. Then, about 4.57 billion years ago, something happened that caused the cloud to collapse.
- The Main Sequence: The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium.
- Core Hydrogen Exhaustion: All things must end. That is true for us, that is true for the Earth, and that is true for the Sun. It’s not going to happen anytime soon, but one day in the distant future, the Sun will run out of hydrogen fuel and slowly slouch towards death.
- Final Phase and Death: Once it reaches the Red-Giant-Branch (RGB) phase, the Sun will haves approximately 120 million years of active life left. But much will happen in this amount of time.
Ice giants are mostly water, probably in the form of a supercritical fluid; the visible clouds likely consist of ice crystals with different compositions. Despite their cold temperatures, they still support giant storms, much like Jupiter’s Great Red Spot or Saturn’s large, seasonal outbreaks.

Feb 6, 2020 · However, recent evidence has shown that Mars may still have water lurking just beneath its surface. Mars may escape the sun’s actual reach — it’s at the borderline — but that water will likely all be gone by the time the red giant star takes over the inner solar system.
