what is the difference of ~5.0 to "5.1.*"

In laravel compposer i have this

"require": {
        "php": ">=5.5.9",
        "laravel/framework": "5.1.*",
        "laravelcollective/html": "~5.0"
    },

then I found in the doucumentation laravelcollective/htmlto add this in composer

"laravelcollective/html": "5.1.*"

what is the difference if we use ~ than * ? or how do I read this "laravelcollective/html": "~5.0" and this "laravelcollective/html": "5.1.*"

Thank you in advance.
