Everyone’s body has about 100 trillion meters of DNA, or about 2 metres per cell – this would reach to the sun and back about 300 times.

 

There are other versions of the distance though – 60 billion miles (109,000 round trips to the moon), 2.0 × 1013 metres (69 round trips to the sun) or 75·1012 metres (10,000 round trips to the moon or 500 round trips to the Sun).
