This is my wife Neptune

The asteroid belt orbits the sun, should all of the asteroids be called planets too?

Do they have natural satelites and rotate around their axis like Pluto?

While you're busy 404ing this thread, reminder that there is yet another gay ERP thread up.

No idea.

It is all a fucking lie

Jupiter, Saturn, Uranus and Neptune aren't real planets just clouds of gas floating in space, you can't stand on them.

Only real planets are Mercury, Venus, Earth, Mars and Pluto.

OK, let's assume this is correct (because I'm too lazy to google). I'm not saying you are wrong. Then answer me this, please. What exatly is the difference between planet and a dwarf planet? According to Wikipedia, the term was adopted in 2006., which would mean it's a relatively new term. Is it because NASA hasn't discovered anything significant in the last few decades, so they need to make up new shit just to (appear to) be relevant?

Mass

Because there are plenty of asteroids just further out from Pluto that are comparable size, so their mentality is that by including Pluto they'd also need to add those other asteroids too and things would get crazy. As a compromise they called it a dwarf planet.

Jupiter and Saturn get denser as you reach their cores (immense pressure crushes everything into incredibly dense high-temperature solids, the same as any core). Jupiter may be a gaseous planet, but it's so large that the solid matter is still larger than earth.

OK, I get it. But... Let's use Google again.
Radius of Mercury is 2.439,7 km. Radius of Ganymede, the biggest moon/satellite in Solar system, is 2.634,1 km
Ganymede is bigger than Mercury. Does that mean ''scientist'' will degrade Mercury to dwarf planet one day, too?

Why the fuck do you have so many beta orbiters, almost as many as that whore saturn. And she's got a huge ring on her.

You're always a moon if you orbit another planet, no matter how fat you are.

Ganymede is a satellite, not a planet. A planet is a large body that orbits a star. Ganymede doesn't orbit the sun (directly), it orbits a planet. Hence it's a satellite.

They're called Gas giants dipshit. Though apparently Neptune is part liquid.

>Hence it's a satellite.
Yes, but is bigger than the actual planet. Mercury. And Ganymede it will stay satellite. My question is, since it's bigger than the planet, will they degrade mercury to dwarf planet?
Not to mention that Mercury doesn't have the rotation like other planets. One side is always looking at the Sun, like it's ''locked''. Kinda like our Moon.

There are seven moons larger than any known dwarf planets. Our solar system has more than just one dwarf planet too. The kuiper belt (much larger asteroid belt beyond Neptune) contains Pluto, Haumea and Makemake. There's also Eris. Pluto got knocked down to dwarf classification after we found there are a ton of other plutoids in the kuiper belt and it wasn't unique. It doesn't make sense for pluto to be a full planet when Eris is larger and there are plenty of other ice dwarfs in the belt alongside it.

>That is, it is in direct orbit of a star, and is massive enough for its gravity to compress it into a hydrostatically equilibrious shape (usually a spheroid), but has not cleared the neighborhood of other material around its orbit.
there you go

man why jupiter so scary tho?

>For many years it was thought that Mercury was synchronously tidally locked with the Sun, rotating once for each orbit and always keeping the same face directed towards the Sun, in the same way that the same side of the Moon always faces Earth. Radar observations in 1965 proved that the planet has a 3:2 spin–orbit resonance, rotating three times for every two revolutions around the Sun. The eccentricity of Mercury's orbit makes this resonance stable—at perihelion, when the solar tide is strongest, the Sun is nearly still in Mercury's sky.

Because the name of the planet is Jew Peter.

Are you from the future? We don't know what the core of Jupiter is made of, let alone well enough for you definitely tell anyone that it is smaller than Earth or what it's like there. Theories range from potentially 12 times LARGER than Earth (calculated by gravitational measurements and mass of non-hydrogen/helium elements) to completely absent (theoretical).

Being in the planets atmosphere the planet would be loud. Being "near" the planet would be silent because sound is vibrations of air molecules, which the vacuum of space would not have.

>we won't colonize any stellar bodies in our lifetime
fuck

Not necessarily, because Uranus has a gravity less than Earth's, while Jupiter's is many times greater. Each of the gas giants are incredibly unique from each other. The estimated core PSI of Jupiter is 650M. Earth's is only 52M. So long as Jupiter has the non-hydrogen/helium mass to support it, it will have a hulking solid core. Emphasis on the "so long as."

You can read a study on it here: cds.cern.ch/record/330644

>mountains of diamonds
Funny you mention that because it only takes 725K PSI at 2,000F to form diamonds. Compared to its 650M core, that means it begins to happen only a fraction of the way into its depths, when it's still gaseous. You could have literal diamond rain in Jupiter, assuming the carbon to support it.

So, if you are on the spaceship and you are near the planet when it explodes - cos Death Star and such - would you hear it?

The matter would be scattered outwards and would be incredibly loud to anyone not immediately killed by coming into contact with it. Chips of paint in space can kill on contact, let alone the explosion of a planet. The noise would come from the vibration of the scattered particles themselves, but as you can imagine they'd be moving pretty quickly.

It's just an arbitrary definition that's just used to highlight more significant objects in the solar system. Just go with celestial bodies if you want a consistent definition.

Would Neptune like Neptune?

Neptune is the big unredeemable cumrag

Nep nep

"Dwarf planet" is a misnomer, it wasn't reclassified because it's too small, it was because it's now considered part of the Kuiper Belt and therefore hasn't "cleared the neighborhood" of its orbital region.
It is much less massive than any planet, 1/20th the mass of Mercury and 1/5th the mass of Earth's own Moon. It has an elliptical and tilted orbit that even takes it within the orbit of Neptune, suggesting it didn't form within the Sun's accretion disk as the planets are believed to have done. Its primary satellite is half the size of it, large and massive enough that they're arguably a double (dwarf) planet system. Like Ceres, it does not exert a dominant influence within the region of space it travels through, despite being massive enough to become spherical under its own gravity.

Having a solid surface was never a qualifier for "planet" but even if it was, the gas giants do have cores, they're just covered by an enormous atmosphere.

Asteroids WERE considered planets when they were discovered, by the mid 1800s astronomers had identified over 20 "planets" between Mars and Jupiter. Most of the largest asteroids in the Asteroid Belt were given proper names in that period for that reason. As observations and theories developed, it was agreed on that they were clearly not the same kind of significant body as a planet proper and redefined/classified as "asteroids."

Get your facts checked, everyone knows Uranus is the real whore.

Uranus is so fucking boring, if its tilt wasn't fucked it would have literally nothing going for it. Even its moons are boring, it has more major moons than Jupiter but they're all just dead frozen rocks, only cool thing about them is the Shakespeare naming scheme.

What technically constitutes a gas planet given that Earth/Venus has a gaseous atmosphere too and the gas planets have liquid and solid closer to their core? Just the composition of the elements as we normally view them on Earth? (e.g. Hydrogen is usually gaseous in earth)

Of course, my theory seems to miss out on planets that don't have atmospheres but it was an interesting thought

Some say that the gaseous planets have a slushy core and not solid though

Left is Uranus and right is Neptune.

Bump

There isn't a hard definition (the IAU only defined "planet" itself in 2006), but generally speaking the "terrestrial" planets are overwhelmingly composed of heavy elements (like iron) in solid or liquid state and having a significant atmosphere is actually fairly rare; there's at least a dozen objects in the Solar System that could qualify as "planet" in the right position but only Earth, Venus, and Titan have really substantial atmospheres, even Mars's atmosphere is only around 1/20th as dense as Earth's on average.
Uranus and Neptune have cores that are similar in composition to terrestrial planets, a molten/solid core of mostly iron and nickel. Their atmospheres are also significantly different than Jupiter and Saturn's; all are very largely made up of hydrogen and a small but significant percentage of helium, but the "ice giants" also have a mixture of "ices" like methane, ammonia and hydrocarbons that give them their distinct blue and blue-green color.
Jupiter and Saturn are "pure" gas giants composed of hydrogen and helium to the core, literally. They still have heavy elements mixed in (each several times more than the entire mass of Earth) but they're generally made of the same stuff in the same proportions as the Sun and other stars. If they were massive enough to trigger nuclear fusion in the core, that's exactly what they would be. As they are, their cores are probably mostly oceans of metallic hydrogen around a solid core of heavy elements under extraordinary pressure. By volume, all of the "gas giants" are actually mostly liquid, as their hydrogen and other gases quickly condense under the pressure of the atmosphere above them; Jupiter's gaseous atmosphere is "only" around 3,000km thick.

Terrestrial planets lack the huge quantities of hydrogen because all of the gas in the inner Solar System went to either the Sun or Jupiter, while the outer planets were all far enough apart to overcome Jupiter and each other's pull or too far to get any.

It means you're retarded.

Probe Uranus

On the surface yes but deep in the crust there's a gigantic ocean full of liquid water. Just like on Earth we have a hidden ocean that can refill all the surface oceans three times over. If we can figure out how to purge Venus' atmosphere enough to where the surface doesn't crush people and can melt solid metal abd open up that ocean we'd have an inatant perfect colony world with atmosphere and warm tenperature. Nuch better than on Mars.

Unfortunately Mars would be mure easier to terraform. You're talking about completely changing the atmosphere of an entire planet. One whose atmosphere hates everything

Because it's a giant chaotic ball of death that could engulf the Earth. I did hear on here at one point that it's what keeps us from being constantly being bombarded by shit from space though, so that's kind of nice. I don't know how true that is.

Venus alreqdy has water though
We just need to figure out how to bleed out the nasty part of Venus' atmosphere to a stable one. And then whe crack open that hidden ocean getting a habitable world with atmosphere and magnetosphere already there. Much easier, safer, closer and faster than making Mars a colony.

The key is figuring out how to vent an entire planet
I'm all for colonizing Venus, especially since it's way closer, making bringing materials and supplies to the planet much faster than Mars
But the bleeding issue might take time, and people are impatient.
