Density Of The Solar Core

Mon Nov 24, 2008 12:39 pm

This is for all the Astronomy buffs out there... Just a question. I recently read a short story that involved a vehicle traveling through the center of the sun. While the steps taken to cancel the effects of extreme temperatures, and even more extreme radiation were impressively plausible, one thing got me thinking.

I know that the state of matter throughout the sun is largely plasma. But is there any portion of the sun that is literally denser than any known solid? I would think so, given that it is a body whose diameter is greater than Cislunar space. The story didn't cover this, so I was left to wonder. Thanks in advance to anyone who knows. I haven't met with much success online.

Well, yeah. The core. Where the nuclei have to be squeezed so close together that they overcome their electrical repulsion and the strong nuclear force takes over.

The average density of the Sun is 1.4g/cc. But, according to Wikipedia (which is NEVER WRONG  Wink ) the density of the core is 150g/cc. Water (on Earth) is 1g/cc and lead is 11.3 g/cc.

So assuming you had something that could survive the radiation and heat, the solidity of the core would round to impassable then?

I can only imagine what the core density of a hypergiant like Eta Carinae must be...

The Suns Core Density is Constantly Changing.

As every second the Sun looses 4 Million tonns of Matter a Second by Energy Conversion Nuclear Fusion that is.

Also at over 15 Million Degrees the Suns Core is not agood place to visit, Should the Ships Sheilds Fail the contense would be gone so quick they wouldnt notice.

The only Info about the Ships Demise would emerge at the Suns Surface in around a Million years or so as a Slight Increese or Decreese in Solar out put.

Hope the Crew packed there Sun Block 10 Million.
