Our Place in Space is part of £120m government-backed Unboxed festival spanning UK over coming months
A glowing silicone sun measuring 2.3 metres in diameter and a pinhead-size Pluto have been brought down to earth in an extraordinary scale model of the solar system aimed at giving the public a true sense of the huge size of space.
The six-mile (10km) riverside sculpture trail opens in Derry on Friday as part of Unboxed, the £120m government-backed celebration of creativity that spans the UK over the coming months.
