GREENCUBE (IO-117) is an amateur radio satellite from Italy, launched on July 13, 2022 from Kourou, French Guiana. It orbits 5,843 km above the ground, far above the low orbits most satellites use, once every 224.1 minutes.
The gold ring is its orbit, and the line drops to the point on the ground under it. Inside the white circle it is above the horizon. Drag the globe to turn it, pinch or use the buttons to come closer; the target button brings you back to the satellite. The 2D map shows its path over the ground for the next lap: gold where it is in sunlight, dashed where it is in Earth’s shadow.

It passes straight overhead between latitudes 70° north and 70° south, and it rises above the horizon everywhere on Earth.
A satellite shows only when your sky is dark and it is still in sunlight: in the hours after dusk and before dawn.
The app works out its passes over your exact location, alerts you before one, and leads you to it with an arrow in the camera view.
Orbit measured November 13, 2026, from CelesTrak. Heights are above the ground at the equator. Page updated November 14, 2026.
The map on this page shows where GREENCUBE (IO-117) is at this moment, the path it will follow over the ground for the next lap, and the part of the Earth it is above the horizon for. It is worked out from the latest tracking data.
About 5,843 km above the ground.
About 5.71 km/s, which is 20,600 km/h. One lap of the Earth takes it 224.1 minutes, so it goes around 6.4 times a day.
No brightness estimate. We have no brightness estimate for it, so we cannot say how easy it is to see.
