What is found on the surface of Ceres?
The surface is a mixture of water ice and various hydrated minerals such as carbonates and clay. Cryovolcanoes such as Ahuna Mons form at the rate of about one every fifty million years. In January 2014, emissions of water vapor were detected from several regions of Ceres.
Is there oxygen on Ceres?
Ceres may have a thin atmosphere and possibly an ocean of water beneath its surface. No one could live unprotected on the surface, but future astronauts could mine water from Ceres to create oxygen and rocket fuel. Gravity on Ceres is about 2.8 percent of that on Earth.
How many planets in our solar system are including dwarf?
eight planets
What does gas giant mean?
A gas giant is a large planet mostly composed of helium and/or hydrogen. These planets, like Jupiter and Saturn in our solar system, don’t have hard surfaces and instead have swirling gases above a solid core.
Could life exist on a gas giant?
In terms of life developing on a gas giant? Sure, it’s possible. At best you could have some form of single cell extremophile organism in the uppermost atmosphere. Even this however is unlikely, as Gas Giants are stupidly hot; what their outer atmospheres lack in heat they make up for in cell crushing pressure.
What are 3 characteristics of gas giants?
Unlike terrestrial planets whose composition is rocky, gas giants have a mostly gaseous composition, such as hydrogen and helium. They do have some rocky material, although this is most often found in the planet core. The four gas giants are (in order of distance from the Sun): Jupiter, Saturn, Uranus, and Neptune.
Can you fly through a gas giant?
A Solid Core In the distant future, engineers may be able to build a spacecraft that can withstand the conditions inside a gas giant like Jupiter, but even if they do, the craft won’t be able to fly straight through the planet.
Can you walk on Venus?
Walking around on Venus wouldn’t be a pleasant experience. The Venusian surface is completely dry because the planet suffers from a runaway greenhouse gas effect. Venus’ gravity is almost 91 percent of Earth’s, so you could jump a little higher and objects would feel a bit lighter on Venus, compared with Earth.
