My current star system is "Alpha Gloomii 84 III a" and "b", "b"...

In Starbound, you take on the role of a character who’s just fled from their home planet, only to crash-land on another. From there you’ll embark on a quest to survive, discover, explore and fight your way across an infinite universe.
You’ll encounter procedurally generated creatures and weapons, discover populated villages and abandoned temples. Explore planets dotted with dungeons, eyeball trees and treasure. Make use of over a hundred materials and over one thousand in-game objects to build a sprawling modern metropolis or a sleepy secluded cabin in the woods, and do all of it alone or with friends!
In regards to world size, yes, worlds can be very differently sized. Also, unlike Terraria, if you walk far enough to one side you end up back where you started, which I like.
Right. It seems like Starbound planets are about as small as the small worlds in Terraria and as big as the very large ones. That said, there are more things in Terraria worlds than in Starbound ones. That said, a small Terraria world seems much richer in stuff to do.
Well, after being on three different planets, they seem to be at least as large as a Terraria large world. I just finished wrapping around a desert planet that had snow in places. But, I also found a temple. I'm still exploring the planets in the system I started in. The original two that I found are just two among a few others revolving around a sun, which I failed to notice on my initial view of the navigation system, which I've gotten used to.
Yes, if you compare a world to a planet, Terraria offers much more diversity in one world of biomes and things to do. Although Starbound seems to break large biomes up into planets, moons, and asteroid belts.
Oh and did anyone else notice the "FTL Drive?" =)
FTL (the game) didn't invent that term, it's a common sci-fi trope.

The "bling" sound is probably you picking up pixels the monster dropped when it died.
Also, copper ore remains important to repairing tools (well any ore, but copper seems to be best bang for the buck).
I don't think it's picking up pixels, as I know that sound. And yes, I haven't been refining my copper ore, but I've been using it to repair my diamond drill. It only takes one ore to repair one bar, which is pretty cheap, but I have plenty of copper.
Yeah, there's not much to spend ore on yet... I ended up collecting over 1000 bars of gold, then crafted up diamond drills for both my kids and spent a chunk of that. :)
