COSMOS 2428

COSMOS 2428 is a satellite from Russia (and the former Soviet Union), launched on June 29, 2007 from Baikonur, Kazakhstan. It is in a low orbit, 840 to 858 km above the ground, and goes around the Earth every 101.9 minutes: 14.1 times a day, at 7.43 km/s (26,700 km/h).

Where COSMOS 2428 is right now

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.

Can you see it?

Without a telescope

Yes, under a dark sky

On a good pass it is a faint star to the naked eye: magnitude +3.1 at its best. City lights hide it.

From where

It passes straight overhead between latitudes 71° north and 71° 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.
