Understandable. I saw something similar to this on something aired by the National Georgraphic called Extraterrestrial - however, I didn't completely agree with the science behind it. That's why I asked. However... Why would there be a storm? The subsolar point is basically the hottest place on the ...

The planet is terrestrial, weighs in with a radius of 8,097 km, 4.5 million kilometers from its host star which is class M with a radius of 0.11 Rsun.

In one of my systems, I have a planet tidally locked to its host star. Now obviously this means one side is completely frozen, the other one is in perpetual daylight. There are three things I'm not very sure on, which is why I'm posting: 1) Wouldn't there be a massive storm at the point of most sunl...

How long will it be before 1.4.0 is released?

Yeah, I would figure that. Otherwise, that means that Earth would be a nice, balmy 1 degree farenheit.

Does the temperature readout take binary systems into account?

How accurate is the temperature readout in Celestia? I normally use it to gauge the habitability of my planets, and I'm just wondering if I can rely on it, or if I'll have to do the math myself.

I just upgraded my video card/chipset drivers and found myself with the same problem. I have an image of the occurence:



Damn you, Intel. I wanted spec maps and bump maps.

How would I go about doing that, then?

(That is, modifying the central star to orbit a barycenter.)

I'm trying to set up a binary system where a white dwarf orbits a larger host star. I know how to do this if I'm creating the system from scratch, but the host star is already existant. I don't know how to put a star in orbit around an already existing star.

Any help?

What I'm looking for is a star slightly larger than Sol with a nearby star, under four light years away. I would like at least one of the stars to be part of a constellation. I've found the best candidate system so far; Epsilon 1 Lyra and Epsilon 2 Lyra... but there's one problem. Epsilon 1 Lyra Abs...

So what types of stars would be able to support 'stable' systems, similar to our own?

I've been searching for an answer to this particular subject, but I've come up short. I'm searching for a way to accurately calculate the orbital velocity of an object around its host star. Right now, most of my planets in my systems are either going too slow or too fast, and would obviously either ...

So there's very low probability that a stable planetary system could have formed around this star?

TET1 Tau Abs mag: 0.41 Luminosity: 58.4x Sun Class: G7III Surface temp: 5,070 K Radius: 11.19 Rsun Sol Abs mag: 4.83 Class: G2V Surface temp: 5,860 K For comparison. There wouldn't be problem using Theta Taurus, would there? Secondly, if I'm moving the world closer to its parent star, how far would...

I have an Earth-like moon around a gas giant. Celestia reads that the temperature around the gas giant is aronud 215 K, and around the moon is an even cooler 202 K. According to Celestia, the temperature around Earth is about 260 K - and even Mars is 221 and still relatively frigid. I want living on...

Let's hope they don't start trying to post.

I looked around the nearby area and found Theta Taurus, which is also a binary system about 9 light years away from the Sigma Taurus system. Theta 1 Taurus Abs mag: 0.41 Luminosity: 58.4x Sun Class: G7III Surface temp: 5070 K Radius: 11.19 Theta 2 Taurus Distance: 0.25806 ly Abs mag: -0.02 Luminosit...

In this case, wouldn't an upgrade be ideal?

Yes, thanks. Very helpful.

The star name "Sigma Taurus" is not defined in Celestia. ("SIG1 Tau" and "SIG2 Tau" are defined, however.) It's not specifically defined as Sigma Taurus, but can be selected by typing it as such. Change the Albedo value to something a lot lower ,try 0.1.Not necessarily accurate but it should do the...
