SL-8 rocket body (19257)
SL-8 rocket body (19257) is a spent rocket stage from Russia (and the former Soviet Union), launched on June 21, 1988 from Plesetsk, Russia. It is in a low orbit, 748 to 775 km above the ground, and goes around the Earth every 100.1 minutes: 14.4 times a day, at 7.47 km/s (26,900 km/h).

Can you see it?
From where
It passes straight overhead between latitudes 74° north and 74° 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.
When it passes over you
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.
