A newly discovered asteroid is sticking close to our sun - much closer than our own planet Earth.
The asteroid, called 2021 PH27, completes an orbit around the sun every 113 days and comes within 20 million kilometres of our star.
That gives this space rock the distinction of having the shortest known orbital period for an asteroid - and only the second shortest orbit around the sun after Mercury, which takes 88 days to complete its orbital journey around our star.
