How get properties from object in Laravel

I am beginner in Laravel. I use Laravel 5.8 in my project.

I have this object:

NominatimAddress {#1146 ▼
  -attribution: "Data © OpenStreetMap contributors, ODbL 1.0. https://osm.org/copyright"
  -category: "building"
  -displayName: "99, 9 Maja, Janowo, Olsztyn, powiat pomorski, pomorskie, "
  -osmType: "way"
  -osmId: 142789154
  -type: "yes"
  -coordinates: Coordinates {#1147 ▼
    -latitude: 51.51171143
    -longitude: 11.4023121
  }
  -bounds: Bounds {#1148 ▶}
  -adminLevels: AdminLevelCollection {#1149 ▶}
  -country: Country {#1152 ▶}
  -timezone: null
  -providedBy: "nominatim"
}

How can I get latitude and longitude from this object?
