Chinese/中文：
建议收录所有现实中已发现的所有天体收录到Space Engine。
比如说SIMBAD天体数据库，收录了太阳系外绝大部分已编号和命名的天体。
如果你们可以这样做，为什么不这样做？
还有，你们还不仅不收录所有现实中已发现的所有天体，你竟然还移除了J1407b，这可是唯一一颗可能存在多颗系外卫星的系外行星（有三颗卫星），为什么要移除J1407b，不移除有什么坏处吗？
J1407b明明没有被正式证伪，只是因为太久没有凌日而被认为可能是流浪行星[https://kenworthy.space/projects/j1407b]，建议恢复J1407b到Space Engine里。
English/英文：
It is recommended that all objects discovered in the real world be included in Space Engine.
The SIMBAD Object Database, for example, contains most of the numbered and named objects in the outer solar system.
If you can do it, why not?
And not only did you not include all of the objects that have been discovered in the real world, you also removed J1407b, the only exoplanet that could have multiple exomoons (there are three), why did you remove J1407b, is there any harm in not removing it?
J1407b clearly has not formally been falsified, just because too long considered may be wandering without transiting planets [https://kenworthy.space/projects/j1407b], proposed that restoring the J1407b to Space in the Engine.

I have just answered somehow in another thread. As far as I know, we don't have an estimated distance for the object, which is not considered anymore as orbiting around J1407. When we will have enough data, and maybe a way to represent protoplanetary disks...

[left]Please add the value of cosmic directions (degrees) on the Universe map, otherwise it is almost impossible to travel in the required direction. It would also be nice to divide the Universe map into Upper and Lower hemispheres with different color gradients, although I understand this is more difficult to implement.[/left]

Добавьте пожалуйста значение космических направлений (градусов) на карте Вселенной, а то практически невозможно путешествовать в требуемом направлении. Также было бы неплохо разделить карту Вселенной на Верхнюю и Нижнюю полусферу с разным градиентом цвета, хотя я понимаю это сложнее реализовать.

Spacecraft Flight Planner?
I want to realistically perform advanced rendezvous and Hohmann-transfer flight plans, but due to the lack of a current spacecraft flight planner, I find these difficult. Would it be possible to implement a system where an orbit can be at least roughly predicted after a certain maneuver and a prediction of rendezvous information with another object? (Spacecraft/celestial body)

Thanks
