This is an example for the most recent exo
This forum post has all the information about the exo. What type and tier, what atmosphere level it is, when it appeared and when it will leave. It also shows you where the warp from is as well. If you go to that planet (in this case it says 42 blinksecs off Kol Huroo) you’ll see the planet flying around in the air. You might need to wait around and look in the sky before it shows up. If you have a totem with warp augment equipped to the totem and use it while pointing to the exo world, it’ll save the warp spot to your locations. Put down some warp conduits and interact with it to select the warp location and pay the 3400c fee to warp there. You would need the skill points into the warp distance skill to get to this planet as well.
That’s a very “manual” way to do it. If you go to that forum post for the planet and look at some of the replies you’ll see some people have “completed Atlases” and “location tokens” set up for the world. You can go get a location tokens from one of these people who explore the world’s pretty early into their life cycle. Save the location token and then warp using that location. This saves you the trouble of having to find the planet and using the warp augment to get their yourself.
And lastly you can always ask in the in game chat if anyone is heading there, and then meet up with them so you can get a free ride there without having to worry about having the skill points or using your own coin. If I’m ever going to an exo I’ll usually ask if someone near me needs a ride, sometimes people will announce in chat that they’re heading there. So ask around or keep your eyes on the chat if you need a free ride there.
Hope this short instructional post helps and hopefully I didn’t make anything too confusing. If you need more clarification on anything I put here please do ask
