No Earth-likes. Number Five is a guaranteed waterworld, pretty sure Four is as well. The others are HMCs which I suspect wouldn't even be terraformable.
With experience, you learn what ELWs look like under different lighting conditions and usually don't be fooled. I've only been fooled once, and it went the other way - a world I assumed as a mere waterworld turned out to be an ELW with really tiny landmasses.
But there are plenty of ways to tell an ELW before you actually scan it:
- On the system map, ELWs usually have both islands in the ocean. If the planet is just sea and clouds, it's (probably!) not an ELW.
- Also on the system map, and mentioned by other above, turn on the game's ambient sounds (if you've turned them off) and listen to the "music of the spheres". Each planet type has a distinct sound when you zoom in to it: HMCs have heavy metal distorted guitar thing going; waterworlds have bubbly gushing water. ELWs have some gushing water, some string accompaniment and a tropical bird calling out every few seconds. If you want practice, open the system map for Sol or some other pre-Explored system with a known ELW and listen.
- Look at the little graphic that shows up in the bottom left corner of the main screen. Again, each planet type is different. Waterworlds are always featureless balls. ELWs have a complex land-and-ocean pattern with a distinctive lake/island at about the 2 o'clock position (ammonia worlds have the same pattern). HMCs have a mixture of different patterns, one of which can resemble the ELW pattern but is blurrier and without the lake at 2 o'clock.
