Unknown Astronomy app listed in my iPhone 16's cellular data usage

iPhone 16 .. i go into settings and check out my cellular data usage and select the list to sort by usage. Astronomy is like 5th down and I knew I hadn't downloaded any Astronomy apps yet. I searched my apps, I searched the App Store and nothing not even the icon that it shows is anywhere. This is my only apple product and these are totally new apple and iCloud accounts I am using. I’m just curious any ideas what’s that’s about?
