Neither. Newspapers don't use footnotes, so there is no use for an asterisk. The AP Stylebook entry on asterisks says, "Do not use the symbol. It rarely translates and in many cases cannot be seen by AP computers or received by newspaper or other computers."
It should go after the full stop.
An asterisk typically goes after a full stop (period) when it is used to indicate a footnote or additional information. For example: "This is a sentence.*" The asterisk is placed outside the punctuation. However, if the asterisk is part of a sentence or used in a different context, it would follow the relevant punctuation rules.
The comma would come after it.
Before the number.
A colon is used to introduce a list, a quotation, or an explanation that follows from the preceding clause. For example, "She brought three things to the picnic: sandwiches, drinks, and fruit." A semicolon is used to connect closely related independent clauses without a conjunction, or to separate items in a complex list. For instance, "I wanted to go for a walk; it was raining too hard."
Depending on the situation or sentence in which it is used, a colon could go before or after an asterisk.
