Hello! This is cmdr tulextreme and i present you the "impossibru water world!"

tulextreme · Sep 17, 2017

After almost 2 months zig zagging across the universe this cmdr is close to complete hes journey and since i've made ELITE explorer a few minutes ago, i went through all my relevant discoveries and found this peculiar water world, which imo is totally impossible to exist at these physical conditions!

A Water World smaller than earth with a scorching 351K temp! Sure thing all life in at this rock might be made of pure fire! I prob have pictures of it, but cant find it among my over 5k Elite dangerous Google Photos! Anyway just wanted to share it with u all explorers!

A bit on the warm side, but nowhere near 'everything is on fire' hot.

351K ~78°C

Thx for the math cmdr! Almost @ boiling point them! o7

At that surface pressure it must be pretty close to vapour almost constantly

The boiling point of water at 6 psi = 76.7 C

.39X14.69 = 5.7291 psi so it seems this planet must be rather steamy.

I suggest it be renamed to Sauna

Probably only rains in winter

True, i was just thinking of that.

The poles on this plant might be a great place for a comfortable steam bath.

The equator great for cleaning your hull as you skip through at speed!

Yeah that water world would be fine, it would be a constant steamy smog over the surface rather than clear seas, The other thing is the CO2... The amount of CO2 dissolved in the water will change the properties a little bit to, though not sure that is in the models.

Many of the Water worlds and some of the ELW's I see are less than 273K, scratch my head at that one. Looking at a phase diagram I guess you can get liquid water down to about 250K at very high pressures. I will have to look next time I see a low temp WW where it fits on the phase diagram.

Stellar forge seems pretty wonky at times, I see ice worlds with very high surface temps close to the star and various such oddities.

I wonder how far it is from the star? Can we tell that?

Pirin · Oct 16, 2017

It seems you found a steam bath planet.

0.55AU according to the pic (semi major axis).

Ah, so that's what that means. Ta.

Speccy · Oct 16, 2017

To be precise, the semi major axis is actually the furthest distance from the star the planet makes in its orbit. But seeing as the orbital eccentricity is pretty low (the deviation from a perfect circle), it's basically equivalent to the orbital radius in this case.

That is a useful piece of info, thanks Speccy.

Blindingly obvious to them as knows I suppose.

You can also work an average distance out from the orbital period, in this case 195.8 days.

Well, almost. It's half of the major axis, which is the longer axis of the ellipse. Since the parent body is at once focus of the ellipse, the longest distance in the orbit can be quite a bit bigger than the SMA, depending on the eccentricity.
