It's A Moon or Rock ? OR something Strange !
The earth's moon was formed in the nascent stages of our planet. When a massive impact with another stellar object cause a huge amount of material to detach and form into its own piece of rock.
But not all moons are formed this way some are meteors that have been captured in orbit of a planet and others simply form in place a process that had never been seen before until 2013. Near the edge of the rings around Saturn a small 1.2 mile wide formation was spotted because it reflected a lot more light back than the dust that surrounded.
Astronomers were excited to find that they'd be able to witness a moon being formed. But these hopes were dashed in 2014 when images failed to find this new moon that had been called Peggy the following year when the Cassini probe took images of the rings Peggy was once again seen.
But this time it was a lot smaller and there was a large rock orbiting very close to it it's thought this must mean that Peggy collided with another piece of rock and broken too.
Peggy has now moved further into the rings. It's thought likely that it'll contact a lot more material with the ring itself and potentially become two or three times the size it is now over the course of a few decades or it'll be broken up and returned to the dust from where it came.
As the formation of a moon like this has never been documented no one's sure quite what will happen.
