Modern catalog uses IAU axial tilt notation, which describes celestial coordinates of the north pole while looking from the body. SE supports this as a RotationModel tag: RotationModel "IAU" { Epoch 2451545 // J2000 PoleRA      269.9949 // degrees PoleRARate  0.0031 // degrees/century (pre...

64k - 8x improvement, required 16k and 32k.

25308 How many real exoplanets are in the new version of the program as of right now? It is a 1.5 years old, 3566 confirmed planets, 1804 candidates and few dozen of manually tweaked ones. 25345 I think one day,those jets will be volumetric too,just like those nebulas. They are volumetric, like com...

Thank you, added to steam update.

JackDole: I assume that the letter 'H' stands for the 'RotationPeriod' and the letter 'P' for the diameter or the radius. (I took it as radius.) You are wrong, H is the absolute magnitude (AbsMagn in SE). I don't know what is P/d, but certainly not a size. Size can be estimated from absolute magnitu...

Thanks, integrated.

25280 Thanks HD, so there will be two versions if I understand correctly?  The free planetarium version which is how SE is right now and the game version which will be available for a small charge?  I wouldn't mind a yearly fee if it meant that a new version comes out every year!  20/yr is very rea...

25252 I know it is being released on Steam but will it be released on the website at the same time? I like downloading things from here. No. This would require implementation of DRM protection and auto-update system. Maybe in future, if I decide to go out from Steam. 25252 Two suggestions for a lat...

24842 It's pretty easy to determine stellar class and color using photographic data (B-V) and absolute magnitude and distance. No, it is not. How would you determine to whuch branch star belogs, if those "branches" are so fuzzy? Only white dwarfs can easily be classified (well, most of th...

Wow indeed impressive!

China continue doing this. I forced to ban out the whole country.

Site is currently under attack from China. You may have errors, slow response and other problems until this stops. CPU load is about 100% and database requested too much. Hey, China, what's wrong with you?

You should also check if parallax > 0, because some stars with parallax < 0 may still have reasonable parallax error.
