Gas Giants Gobbled Up Most of Their Moons
More moons for this planet!

Even though our Solar System’s gas giants vary widely in size and mass, they do have something in common. Each planet is roughly 10,000 times more massive than the combined mass of all their moons. During planetary formation, rocky moons grew out of the solid material surrounding each planet. As these moons grew larger, leftover gas slowed them down, and they fell into the planet to be consumed. The moons we see today were the last ones to form around their parent planets, after the gas had dissipated.

I trying to think about this planet Jupiter, it having too many babies, more moons. I think some of those moons might be like planets. In natural study, astronomers have looked on this planet to search life and extinctions. I always look and think about Jupiter and i wonder why this planet is giving more moons. This thing is like the movie 2010 (i can't remember the rest of the name). Which that astronomers found life and Jupiter swelled up and exploded and turned into the star.

So i think this would happen or not, Jupiter is the main planet and and it have alot of main characters in finding life and growth of thousand of moons!
 
Indeed, our views of planets have changed a lot over the past few decades. We now look at them as we would planets.

Then again, our descriptions are kind of arbitrary. In nature, they're all just clumps of stuff moving in big circles, some a little bigger than others.

Well, arguing whether some heavenly body is a planet or not is like arguing how many trees make a forest.

It's 40. 40 trees makes a forest. 20-40 makes a copse. Less than 20 it's a stand.

Two trees is referred to as a 'dunce' of trees. One is a 'lone' tree.

What makes Jupiter a planet is the fact that it orbits a star and that it is not large/hot enough to produce light by itself.

What makes a moon a moon is that it orbits a planet, not a star. The largest moons in this solar system are larger than the smallest planets.

A third order is planetoids. These are bodies that orbit the sun, but are considered too small to merit the term planet. The asteorids are a group of planetoids that originate in the asteorid belt.

Then there are the creduloids. I don't know what they orbit...silly ideas, I think. ;)

Brilliant - however in America it's legitimate to refer to single examples of the Pinus genus as "Lonesome".

Since the International Astronomical Union doesn't have its act together on the definition of a planet, I'm surprised you do...

People of Earth, your attention please. As you will no doubt be aware, due to the building of a hyperspatial express route through your star system, all planetoids and other rubble will be scheduled for demolition. The process will take slightly less than two of your Earth minutes. Thank you.

Oh, and as gas giant dwellers, we consider anything smaller than Neptune a planetoid.

That's a good working definition, but the trouble with using it is that moons don't really orbit planets, so much as they (and the planet) orbit a common centre of rotation, at the barycentre of the system. (And in fact, this can be applied to any orbital system.)

An ad hoc definition might be that when the barycentre of a two-body system lies within the radius of one body, then that body is the planet, and the other body is the moon. If the barycentre lies outside both bodies, then you've got a double-planet system; in fact, if the two bodies were Jupiter and the Sun, the barycentre is outside of both.

This gets ugly, quickly, for multi-body systems; ignoring the effects of the rest of the solar system is of course the conventional approximation.

I not sure if that Jupiter have enough heat to explode as a star. maybe in other way those red spots could expand and make the planet shrink and then explode into a star. Once at this time, at 2^_3 3rd's of life time is equal 3.6 light years equal 3 years, July 2009, could be estimated time for Jupiter's big bang. In this theory, Jupiter do not affect us by explosion because if you know the size of our sun can get us, so Jupiter is even smaller and long away away from us. I not sure i correct this.

Jupiter does not have enough mass to support stable core fusion reactions, not by a long way. The minimum mass required to be a star is between 75 and 80 times the mass of Jupiter. The minimum mass for any fusion reactions (even unstable ones) is about 16 times the mass of Jupiter (here, here, and just about anywhere you find on google if you search on "Brown Dwarf").

In other words, Jupiter isn't going to turn into a star. Not now, not ever.

This makes no sense whatsoever.

Hi Jupiter is too small for the hydrogen at it's core to fuse, which is why the aliens have to do it in 20_Something by Arthur C. Clarke.
