I just wanted to know approximately how frequent updates were released.
Many new users ask this same question. You can find even in this thread some examples. The answer is always the same. It will be ready when it is ready. I know it sounds rude, but bare in mind that this project was started by a single person in its free time. Now there are a pair of additional contributors and there's a bit of money for it to keep growing, but there are many things to improve (detect and correct bugs) and implement (parts of the algorithm that have to be changed continuosly to adapt to new hardware updates). All of this makes SE a long run project. There are updates each two months, but sometimes it is way more time and others it is just a matter of weeks between them. There is no predictability on this. Problems that might seem insignificant can always turn out to be large and complex implementations might be done rapidly sometimes.
Doe anyone has play Universe Sandbox? It is a dazzling Universe Sandbox where you can create systems and stellar objects with ease. You should give it a try.
I've never played it myself but many here obviusly had. Again, I reccomend you use the search tool. There are even entire threads about this topic, like
