If a sunlit part of the Earth is visible from a satellite,
so is the Sun! But 20 degrees from the terminator, more than
400 km above you is in shadow, so in this case it is not sunlit.

Also, some programs keep predicting even though the elset
indicates it should have already decayed. If it for some
reason is decaying slower than predicted, it is possible
that the actual average period is higher than predicted,
and the decaying object is a little late.
