After 8 hours exploration skill level 18

We have accumulated uranium resources for a few days, and in a few hours we will be at exploration skill level 18.
I have been upgrading for a really long time.
This game is bound to get tired because you just click on the upgrade and there are no other events at all.

However, if the exploration skill level is 18, you can find the planet.
I have done a bit of research on the planet, and this seems to be a probability game.

It is said that exploration does not mean that the planet can be found unconditionally, but it is very likely that it will not be found.
If you do not have a planet around you, you can waste a lot of resources and time.

I wonder what my luck is like.
