I was searching for red supergiants and i found this odd system:

RS 1137-7-0-0-0 1



the first planet is going to plunge inside the star!

here it is, before dying a fiery death:


I guess he´s boned, burned into oblivion


Then, WTF, he passes through the star and leaves unscrached!

Yikes, I remember my friend showing me a sundiving planet he'd found in SE once, but that wasn't with a red giant! surprised

Oddly, it's not entirely unrealistic that the planet comes out again in this case, as red giants are incredibly undense. The outer parts of red giants can be less dense than our Sun's corona, which is already less dense than Earth's atmospere at a hundred km height. Considering the highly elliptic nature of the orbit, its speed must be pretty great when it sundives, so I guess it's possible it wouldn't lose enough speed to stay inside the star for one or two orbits.





I occasionally stream at http://www.twitch.tv/magistermystax. Sometimes SE, sometimes other games.

No, No, ANY planet going into a red giant would be vaporised, the atmosphere would not be intact.....

It's a gas giant, the entire planet is one big atmosphere.

apenpaap is right. While this would certainly be destructive to the planet over a longer timescale, it would not be instantly fatal. We have observed comets that can pass through regions of the sun that have similar temperatures and pressures, and even those small comets a few hundred meters wide can survive the journey. A massive planet would certainly experience mass loss and deleterious effects, but it would take many thousands, if not millions, of years to erode it completely.

Of course, that depend on the planet not going too deep into the star. The one shown above does go pretty deep, and it would be destroyed far sooner, maybe even on a few passes depending on the composition and bulk properties of the planet.

No. Gas giants do have a large extended atmosphere, but their deep cores are made of rock and metal.

Has this been proven?

I know, it was a kinda non-serious statement.

The pressure causes the hydrogen to be an extremely dense global ocean liquidy thing, mabe even solidifying one you go deep enough.

Depends on what you mean by "proven", but there is extremely strong evidence for it.

Ok, Harbinger, what i mean with the "Should be better dry .", it´s the collision, sould animate the impact to the star and the planet should be destroyed before leaving inside! Ok? wink

Ok. Well SpaceEngineer has already said that he wants to make collisions more realistic in future versions. In the current version it's not possible.
