Neptune, the Roman god of the sea
Is even MORE blue than Uranus
Though they are both just as wide
(Being almost the same size)
They are also similar in their gas
But Neptune is NOT turned on its side

Neptune, of all the gas giants
Appears to be most dense
And, compared to
Uranus, Jupiter and Saturn
Neptune is also the smallest

Neptune has over ten moons
A special one is Triton
Special for something so near
(And also to us rather dear)
Its very own atmosphere!

Most moons don’t have the gravity
To hold such gases down
But Triton’s mass gives it a way
With a “bubble” all of its own
