A Facebook conversation with Royal Museums Greenwich reports the following:
[T]he sculpture was returned to its owner ‘News Print International’ (sic) after its loan was complete. It went to their print works in Broxbourne, Hertfordshire, although whether it is still there, we do not know.
Designed by Christiana Garzia, the piece was installed in 1999, a public sculpture commission sponsored by The Times newspaper and, subsequently, under the care of the Royal Observatory until 2015, when it was removed.
Newsprinters Broxbourne is the printer to many of the UK’s newspapers, including The Times.
