Is Ganymede a planet?

Jupiter’s moon Ganymede is the largest satellite in the solar system. Larger than Mercury and Pluto, and only slightly smaller than Mars, it would easily be classified as a planet if were orbiting the sun rather than Jupiter.

Is Ganymede icy or rocky?

Ganymede has three main layers: A metallic iron core at its center, a spherical shell of rock (mantle) surrounding the core, and a spherical shell of mostly ice surrounding the rock shell. The surface is the very top of the ice shell. Scientists have discovered irregular lumps beneath Ganymede’s icy surface.

What planet does Ganymede belong to?

Jupiter

Ganymede, the solar system’s largest moon, orbits Jupiter, the solar system’s largest planet.

What planet is Uranus?

Uranus is the seventh planet from the Sun, and has the third-largest diameter in our solar system. It was the first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel, although he originally thought it was either a comet or a star.

What planet is green?

Uranus

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 and ammonia ice.

How is Uranus blue?

Uranus gets its blue-green color from methane gas in the atmosphere. Sunlight passes through the atmosphere and is reflected back out by Uranus’ cloud tops. Methane gas absorbs the red portion of the light, resulting in a blue-green color.

What if you fell into Uranus?

Video quote: You would eventually enter uranus's upper atmosphere where you would fall through clouds of frozen methane that is mixed with hydrogen.

What if Earth had rings?

The rings would probably reflect so much sunlight that the planet would never fully plunge into darkness, but remain in a gentle twilight even in the depth of night. During the day, the rings could potentially cause light levels on Earth to skyrocket [source: Atkinson].

What is the stinky planet?

NASA astronauts used technology to determine that Uranus likely smells like rotten eggs. Yuck!

What if you fell into Mercury?

Over time, the symptoms of mercury poisoning would include speech difficulties, lack of coordination, and even vision loss. And if you didn’t manage to get out of the pool, you would surely pass out and die from metal’s fumes.

Can we live on Pluto?

The surface of Pluto is extremely cold, so it seems unlikely that life could exist there. At such cold temperatures, water, which is vital for life as we know it, is essentially rock-like.

Can humans live on Neptune?

Similar to most planets, Neptune is a volatile world with no solid surfaces. Besides, the desolate planet is no place for human life.

What if you fell into Saturn?

What would happen if you fell into Saturn? The atmospheric pressure would increase to 2-4 times that of Earth’s, and you’d begin slowing down. … In the final layers of Saturn’s atmosphere, you would experience temperatures so high that you couldn’t survive.

Does it rain diamonds on Saturn?

About 10 million tons of diamond rain down on Saturn each year. The new molecule is relatively heavy, and when attracted by the planet’s gravity, begins to be drawn downwards.

Can you walk on Saturn’s rings?

You probably won’t have much success walking on Saturn’s rings, unless you happen to land on one of its moons, like Methone, Pallene, or even Titan, which has been considered a potential site for a future space colony. But you’ll want to keep your space suit on, as Titan is a chilly -179.6 degrees Celsius (-292 F).

What would happen if you stood on Pluto?

Video quote: And if you were standing on Pluto during the right season you may experience the dwarf planet's atmosphere freezing. And falling as snow to the surface.

Can humans live on Titan?

Robert Zubrin has pointed out that Titan possesses an abundance of all the elements necessary to support life, saying “In certain ways, Titan is the most hospitable extraterrestrial world within our solar system for human colonization.” The atmosphere contains plentiful nitrogen and methane.

Can we live on Sun?

Well, what would it be like living on the Sun? Firstly, no humans could ever inhabit the Sun. It is a star. Scalding temperatures, nuclear processes, and unexpected lethal bursts make the Sun a deadly world.

Can humans live on Mercury?

Tough Place for Life



It is unlikely that life as we know it could survive on Mercury due to solar radiation, and extreme temperatures.

How long can you survive on Pluto?

As such, there is simply no way life could survive on the surface of Pluto. Between the extreme cold, low atmospheric pressure, and constant changes in the atmosphere, no known organism could survive.

What planet can we live on?

Earth

Earth. Earth—our home planet—is the only place we know of so far that’s inhabited by living things. It’s also the only planet in our solar system with liquid water on the surface.
