After taking that optional astronomy class in High School I thought I had learned most everything basic about the formation of stars. Until I read a recent report from CNN, it appears that a small dim star 500 lyrs away has a gas giant close to the size of Jupiter.

You might say, is that normal?

No it is not, when a star is formed planets are made up of what is left over, gasses condense under the weight of gravity creating more dense elements.

This star, simply is not large enough to have created this planet, nor does it have the gravity to pull it so close, this star is much much smaller than ours and cooler.

Most gas giants form close to the star, and their gravity usually causes them to drift further from the inner orbit of the star. In this very case the stars lower gravity should allow this larger planet to drift MUCH further away, why doesn't it?

Has everything we know of gas giants and their formation been wrong?

Please explain to your best knowledge why and how this gas giant formed.

Please obey all crunchyroll rules.

"There are more things in heaven and earth, Horatio,
Than are dreamt of in your philosophy". Simply stated the current state of Astronomy doesn't have all the answers in a universe of infinite possibilities.If you remember back in the 70's Astronomy thought Neptune Saturn and Uranus and their moons, where frozen static worlds.Along comes Voyager and Cassini and presto they're anything but frozen static systems.What if you add a passing star, other planets, black hole ,nearby gamma ray burst, supernovae, a yet to be discovered object or circumstance , or a binary system into your equation. The variables are infinite but Astronomy's understanding is finite.

It's probably an anomaly. It's like how pluto is the only rocky planet in the outer region of the Solar System, when supposedly only gaseous planets should be on the outer regions.

Its neighbouring planets or something might have collided into it causing it to become bigger, that's my guess (based on the theory of how the Earth and the Moon formed. The hypothesis was that there were two planets that collided creating the Earth's satellite afterwards).

Yea, the theory of Earth's moon is a tricky one indeed, a lot of people say it is from a asteroid colliding with earth and then getting trapped by earth gravity. There is also a theory that it came from earth when earth was forming due to the suns gravity pulling it from earth.

The other thing about "Hot Jupiters" are their size and proximity to their respective stars making them easier to detect .

It really is interesting to think about.

Have you read the theory about how the formation of the Moon could probably be one of the catalysts that allowed life to form on Earth? The formation of the Moon lead to the tilting of the Earth which allowed it to form this magnetic shield or something that blocks harmful Sun's rays. It also allowed for seasons to occur on Earth.

Cosmology is such an interesting subject to read and talk about.

Did you happen to catch the name of this star or did they gloss over that? Also is the planet large or smaller when you say close to the size of Jupiter if it is large than it could be a brown dwarf which would explain much. Jupiter is right on the board of being one there was when I was taking astronomy debate about this.

As for how it formed it could be a brown dwarf and its companion star which would make sense if the brown dwarf stole enough mass while it was developing to get up to it's current size. Wouldn't be the first parasite planet star out there.

The report is on CNN if you want to know more.

What is reported is actually quite common or so our discoveries suggest.

There are nearly 2,000 confirmed worlds going around other stars and what we have found over the last 15 years or so has caused us to re-think how planets and solar systems form.

The database of exoplanets (planets going around other stars) is www.exoplanets.eu (this is the encyclopedia of exoplanets.

Good places to read about new planetary discoveries are:
www.universetoday.com
www.sen.com

On the formation of planets
Even before the discoveries of other and Saturn tended to mess up models of how the solar system formed, Clearly nature knows how to make planets but we have not yet figured it out.

Perhaps there is more than one way to make a planet?
Perhaps they form hot and close to their star and then move outward?
Is it more likely we we have the right idea but don't understand the details?

A lot of question are up in the air at the moment, but that's how science works. We have an idea an test it, discarding what does not work or meet the observations we see in nature, keeping what works. Until we began to discover exoplanets there was no way to test our ideas. Now we see many we had were wrong.

If you are really interested in the current thoughts on how planets and solar systems form then investigate The Nice Model (and The Nice Model 2) and The Grand Tack hypothesis. A recent paper looked at the Grand Tack and did some simulations that provide us scientists what we like most in an idea, testable predictions.

Astronomy is a fast changing science these days, it can take a lot to stay on top of the most recent ideas and consensus that develops.

they'll say it's a planet and then change their mind

i'll never forget u Pluto. you'll always be a planet in my heart

Wow a new type of star system something we haven't run into yet bound to happen I suspect they will figure out why but it may have something to do with the facts HATS-6 and HATS-6b are a red dwarf and a Saturn sized planet. HATS-6b may have been a parasite at one time in its life and fed of its parent star. Wouldn't be the first time this happened we have found parasite systems in recent years.

Yup, there is always an abnormality, wonder if we will ever find a earth-like abnormality. It is possible they found proof that Mars once had lakes.

How about this, then? The star formed, and the gas giant was one of them wandering giants and it got caught in the star's gravity field when it came in too close...
