Objects in the universe

can it become a planetoid instead of exploding?

 

The complete star doesn't explode but it leaves it's core behind. That's the white dwarf, neutron star or black hole, depending on the mass of the former star.

 

Way too massive. It just can't lose enough mass to become an object we might call a planet. Here's a table that describes the fates of various stars:

this comparison always amazes me.........

 

You mean, Lucas was lying to us about Tatooine?

Just so this post isn't completely "noise", I remembered a related post from some time ago.

 

How about this object

 

Wow, I didn't know about that. Very cool indeed! There must be some very interesting dynamics that go into producing a stable hexagon of clouds!

 

I dare to say it's one of the most intriguing universe discoveries after blackholes!
After comming across that news i went to check the month date to see if it was already april 1 (i often loose track on what day of the month is...i guess all man do ) Half of me just couldn't believe that, first reaction was, 'this feels like a prank!...'.

 

Joining in a bit late here... Anyway, please correct me if I'm wrong here: I believe planets a couple of times bigger than Jupiter will have enough mass to ignite and turn into stars. I vaguely remember the term "critical mass" from school, and that critical point would be what limits the seize a planet can have. If it's bigger it will become a star.

 

If I remember correctly, the range of masses, and thus object type, goes as follows:

Gas giant planet - less than 1% solar mass (Jupiter is 0.1% the mass of the Sun)
Brown dwarf - 1% to 8% solar mass
Red dwarf - 8% solar mass upwards

I do recall that the boundary between gas giant and brown dwarf, in terms of required mass, is somewhat fuzzy as I think there is evidence that not all brown dwarf examples have demonstrated deuterium fusion.

 

Sorry but: OMG!!!111 That's more lame than "Steven Wrong".

How the hell can a planet turn into a star? That's garbage physics. It makes no sense and I'm not even an expert on physics.

 

Define planet.
Define star.

It's not a physics problem it's a taxonomy problem.

 

I guess I have some reading to do.
I find it difficult to tell between speculation and facts in this thread.

 

Once the mass is big enough the preassure from it starts the nuclear fusion process - volià, a star is born!

 

Are you sure you're not talking about density of mass?

 

To start nuclear fusion, a star needs to have a certain amount of mass to attain the required temperature and pressure at its core. Thus, the way to turn a planet into a star is to add more mass (a lot more mass).

 

I'm betting there's no chance that our planet would turn into a star or a black hole?

 

No chance whatsoever. I'm as likely to turn into a rabbit as our planet is to turn into a star or black hole.

 

It might have something to do with this

 

Ah, great find! Spontaneous symmetry breaking it is
