Why do du -s * and du -s . show vastly different sizes?

I ran both du -sh . and du -sh * inside a directory, but the values returned by the second one don't add up to nearly the same value reported by the first. 5.7GB vs 1.5 GB. Why is this? Are there some files that the * misses?

$ du -s .
5926440 .
$ du -s *

Solution 1:

The * glob excludes hidden files by default. du -hd1 . shows the expected results - the size adds up to the total shown by du -sh .
