[chorus]
started from some dust, now we’re here
started from some dust, now eight planets are here
started from some dust, now we’re here
started from some dust, now the whole solar system here
started from some dust, now we’re here
started from some dust, now dozens of moons are here
started from some dust, now we’re here
started from some dust, now the whole solar system here
[verse 1]
let’s talk about how the planets formed
accretion and condensation
caused the dust grains to grow
and gave rise to the planetesimals
coalescing planetesimals
collisions fuse planetesimals together
then protoplanets got to form
evolving into planets once they cleared away the nebula

when did this all form?, we can know that
we also know that they formed quite fast
we can use radiometric dating
to know it was 4.6 ga
the formation of the moon was from a giant impact
we conclude that from 6 main facts
collision explains these observations
can’t be fission, capture, or accretion
