What is this?

Now that I'm growing a person I simply can't get enough fruit and thankfully we have a ton of variety available in our neighborhood. But perhaps one of the most interesting and totally new to me options was this  little guy. Unfortunately I have no idea what it really is, the sticker says honeydew nectarine but the sign I bought it from gave information for something called a mango nectarine yet it tastes like a white peach. Anyone ever try this or actually know what it is? So far this baby's favorite snacks are fresh fruit which I am so ok with!
