Sorry, not really enough information to help you, please provide the following:
Minecraft version:
Galacticraft version:
Single player (SSP), Multiplayer (SMP), or SSP opened to LAN (LAN)?
Galacticraft add-ons and other mods installed?
Please provide screenshots / crash report / log as needed.
You should have under your logs/ directory upload your latest.log and under crash-reports/ there should be your "crash-2018-xx-xx_xx.xx.xx-client.txt", post it as well. You can post your log files on pastebin (it's free) and your screenshots on imgur (it's free too)

If your world corrupt and you can't open it, due to ticking entity set the following line to "true" in the /config/forge.cfg

BE WARNED THIS COULD SCREW UP EVERYTHING USE SPARINGLY WE ARE NOT RESPONSIBLE FOR DAMAGES.
B:removeErroringTileEntities=true

You will lose the the item causing the crash, but you will recover the world, just remember to set it back to false after you recover the world!

I think the problem here is most likely that GalacticraftPlanets is not installed, so there is no Venus. In old versions of Galacticraft before build 164 this caused a known crash.

Possibly also because the player did not download Galacticraft from the official source...

@Xen MC please go to the official download site http://micdoodle8.com/mods/galacticraft/downloads and download all three mod files, and use those. (All 3 files must have matching versions, for example 4.0.1.175.)
