BEIDOU-2 IGSO-4

BEIDOU-2 IGSO-4 is a satellite from China, launched on July 26, 2011 from Xichang, China. It goes around once a day, in step with the turning Earth, about 35,791 km up, near longitude 102.5° E. Its orbit is tilted 54.6° to the equator, so instead of hanging still it drifts north and south of the same spot each day.

Where BEIDOU-2 IGSO-4 is

The gold ring is its orbit, and the line drops to the point on the equator it stays over. Inside the white circle it is above the horizon, all day and all night. 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 the same on a flat map.

Can you see it?

Without a telescope

Not without a telescope

At that distance even a satellite the size of a bus is far too faint for the naked eye. In a telescope it is a faint point that stays put while the stars drift past it.

From where

It is above the horizon all day and all night for everyone within about 81° of longitude 102.5° E on the equator, and always in the same part of their sky. From the rest of the world it never rises.
