| quarior14,
I found in the English Wikipedia this article about 'tidal locking'
It is there a formula, how long it takes for a body to become tidally locked.
In an old reddit thread I found this question:
'Can the Earth ever become tidally locked to the Sun so one side is always facing inwards (like the Moon)?'
He has more than 200 comments, I have not read them all.
But there was the question; whether a planet can be bound to the sun, when it and its moon are already bound.
I think that's possible. For example, if the orbital period of the moon and the rotation period of the planet, and the orbital period of the planet are the same length. For example, a year.
I have created such a system.
Code
// Noosu.sc
// Tidal locking
// NOt Our SUn

| SpaceEngine has no information about the escape velocity of the body. That would make a great feature.
Love SpaceEngine!

| Fireinthehole, I think that there is, but it is called first cosmic velocity or something.

| DeathStar, so that's what the cosmic velocity is. Pretty confusing, I don't think that's widely used.
Love SpaceEngine!

| A moon and a tidally locked planet can't have the same rotation period and revolution period, for example, if you put our moon in a 1 year orbit, it wouldn't obit Earth, but rather, the Sun, because Earth's Hill Sphere Radius isn't that large.

| This video has a very good idea of how the planetary rings could look in space engine:

| I wish SpaceEngine is able to show the connecting lines of constellation just like Google Sky Map，thank you！because i want to identify constellations in the real sky with the help of SpaceEngine，thank you！

| I concur with 1984xiegiang1984. SpaceEngine is epic. It has epic features too. But there is one thing missing. That is the ability to create lines. The only function I'm looking for is to select Object A (a set of x,y,z coordinates) and select Object B (a set of x,y,z coordinates) and have a line created between them. Having dealt with 3D programs before, I can't imagine this would be a terribly difficult function to create. It is just two points connected by a line. It doesn't have to be anything fancy either.
Is there any idea on when this function will be available? Maybe SpaceEngine already does and I've just missed it. Are there any other space exploration programs that do have this functionality?

Pretty sure Celestia can, the newest Starry Night is really good with things like that though pretty sure you have to pay for that...

| In orbit, one could also add the distance from the apogee and also see the remaining time before it reaches its apogee distance and perigee.
Also, two fashion could put "Following," he realistic at the time when it enters a sphere of influence, it is attracted by the celestial body and by the time that comes out of its sphere influence, we follow not the other way would be locked, it's one that for now is that by default.
It also has a weird thing, if we make one planet to an atmospheric pressure of less than 0.0500 atm, there are no procedural cloud off Mars that has a pressure of 0.012 atm at the clouds, you can make clouds this pressure and deserts like Mars, the clouds look like Terra out select activities is decency be like sandstorms and see water vapor.
Example, here is a customized desert but the clouds are procedural but almost looks like Terra.
Finally the system for export, it could export the system catalogs planets (one by default), one of the stars (which system is low) and when the galaxy is located. This may be convenient to locate the RA, Dec and Dist for I see no other way to locate because in the debugging mode where there is the coordinates, I do not see any infomation about that
(excluding soon as the center of the system is selected but if we want where we are now to make a customized system where there is nothing, it is convenient.
If you add the fact that you can put it in the editor mode, or put in a corner in normal mode since there are fewer of something written on the debugging mode.
Speaking of editing mode, it is in progress (this after the debugging mode) ?
Otherwise we could add a incone + and - for creating a system's center or galaxies (or delete if a center of a system's center or galaxie is selected) to a system's center and placing it directly into catalogs/Edit_[number]/stars/Stars_[number].sc (or catalogs/galaxies/Galaxies_[number].sc if it is galaxies) (where number is used with the same principle as captures except that here, the number of edition), which avoids this break the head as shown above to find the coordinates (RA, Dec and Disc). Same principle to the other stars but will select the parent (for the first time, it will be the center of the system), what I think is more convenient than typing the code and save it in catalogs/Edit_[number]/planets/Planets_[number] (if -, it removes the selected celestial body).
In fact, this is supposed to be implemented because I do not see in the current version Animated model of Jupiter and you can do this for all the gas giants and ice giants.

| Suggestion for simpler units.
for example
Instead of 1000 km (/s) use 1 Mm (/s) -> like in Elite Dangerous
Instead of 1000 c use 1 kc
Also I wouldn't mind if 1c would show up from 300 Mm. Currently ~0.35 c pops up after 100000 km.

| You may find me silly but it's going to put the Sealevel for config so that it is increasingly obsolete because it could be used to find out how the ocean covers the planet (0 for 0% and 1 for 100%) because although it does not specify the BumpHeight, BumpOffset and Ocean Height and we put a Sealevel any, it is ignored, I hope this will be handed / resolved. In fact, the Lava tag will soon be implemented ?

| Would it be possible to have intergalactic stars? And maybe have stars orbit around their galaxies?

Vector into screen would be moving forward, vector out of screen would be moving backward, so it is already correct.

Sorry that I've made a horrible typing mistake.
