I can't say it it enough, planets are WAY too small, and any decent sized exploration ship can't even fit. My favorite thing about space engineers was the huge planets that you could spend hours just exploring the surface. With the recent chunk update, it would be awesome if planets got overhauled. Also it would be great if the gravitational pull on planets was greater and farther reaching so the stop effect would actually have a purpose. Until they are updated exploring simply isn't worth it as planet bases are impractical and they don't have much in the way of resources.
