EVE New Citizens Q&A

Yes, wormholes are very good place to run exploration sites.
Roam around high sec and find class1 - Class2 - class3 wormholes, higher class wormholes spawn only combat sites.
All the sites named by known space NPC pirate factions are without rats so you only need hacking ship.
Gallente - Imicus
Minmatar - Probe
Caldari - Heron
Amarr - Magnate
If your skills allow then go with T2 versions.

*Remember! In wormholes... D-Scan is your best friend!

WH exploration for relic sites is best in done T1 frigates and up. In my opinion nullsec sansha/gurista is best in covops frigates (including the Astero). In covops frigates, you can avoid most nullsec gate camps. Exploration is by far the easiest and cheapest to get into and can make much more money than miners do once you know what you are doing.

To prepare to not get ganked while analyzing relic cans, set up your overview so it shows only cans, the sun, and ALL ships. Make sure hostile/neutral backgrounds are set to BLINKY so you will notice hostiles right away. Make sure your analyzing window doesn't cover the overview. This way, if someone shows up you will instantly see the blinky hostile on your overview, notice it and be able to GTFO within 5 seconds!

When someone shows up, drop the site and warp to the sun ASAP and cloak up while you start warping. Also, set your default "keep at range" distance to 2,250m. This is enough distance to be able to cloak if someone shows up, but not so much that you cant instantly loot the can when you finish it.
practically ANY ship can kill you if you don't know how to warp away within 10 seconds of someone showing up on grid (ie. within 10k km).
Covops cruisers are more rare, but they can kill almost any ship that is dedicated to exploring. Their major downside however is that they MUST wait about 8-10 seconds to lock on to you, so if you know how to get out within 8-10 seconds of seeing a hostile, you will be fine.
Remember, the default d-scan key is V, press it often while hacking and while moving around, if you see another person's set of probes, the likelihood of getting a hostile in your site is a hundredfold bigger.

The most problematic hostiles in null-sec are gate campers, and exploration hunters (as well as armed explorers in nullsec, especially Astero pilots).

Exploration hunters usually fly stealth bombers or covops frigates/cruisers.
Stealth bombers are the most problematic because they can lock you before you can reasonably warp away. Asteros however are the natural enemy of the stealth bomber (where solo exploration and hunting is concerned), their flight of 5 light drones can destroy practically every solo stealth bomber before they can kill you.

In nullsec, always use dscan to check a gate before you warp to it (unless you are the only pilot in local). If there are interdictors or bubbles on the gate, tread carefully.
Gate campers usually come in the heavy interdictor or light interdictor variety, both use warp disruption bubbles. Everything that doesn't launch disruption bubbles you can warp away from easily. When you see them, decide on a direction to go that is SIDEWAYS to them, not PERPENDICULAR (relative to the gate). When you've decided (before you lose gate cloak) double click in that direction, cloak and activate MWD. If you want to be even faster, overheat your MWD first by shift-clicking it and then activating.
This way, even interceptors will have a hard time rushing over to your last known location to decloak you. If they can't decloak you within 10 seconds, they're almost guaranteed to not be able to find you as long as you keep slowboating to the nearest edge of the bubble to continue your journey.

I would actually recommend sticking with T1 exploration ships until you can get in the astero. T1 exploration ships all have drone capabilities and are much tougher than their T2 covert ops counterparts.

You can run off or even kill a T2 covert ops ship in a T1 exploration ship without issues.

The astero is the golden standard of the exploration profession and something you want to jump into as soon as you can comfortably afford to replace it.

Directional scan yes.
In wormholes you cant see local so you never know how many people in the system with you or whats the traffic while you in there.
Best way is to hit D-Scan after every 5-10 seconds.
Even with that you cant detect cloaked ships and that risky moment is always there.

Scan down signatures and identify the hole, if it is K162 then you need to jump in to know what it is.
There is a lot more tools you can use, google and find your favorite.

For what it's worth, Wormhole exploration can be difficult for new players due to the difficulty the high-value cans have. You can do exploration in lowsec for rewards that are significantly higher than those in highsec, while still being able to train yourself to learn the critical skills necessary to survive in a wormhole (DScan being the most important).

Wormhole entrances can be found everywhere, most frequently in lowsec. Wormholes in higher sec space tend to lead to lower classes. Once in front of the entrance "show info" and check the text. If it does not contain the words "dangerous" or "deadly" accompanying the "unknown space", then it's what you are looking for. Also read carefully the rest of the text about the entrance condition. Indications of end of life or verge of collapse are usually big stop signs if you are not prepared for a much longer trip home ...

Really thanks guys. What you said help me a lot
