The Planets - Neptune.

You will not be expected to remember this information for the exam.

Neptune spins on its axis once in about 16 hours.
The surface temperature of Neptune is about -220°C.

Neptune is the fourth largest planet.
Like Jupiter, Saturn and Uranus,
Neptune is made mainly from hydrogen and helium

atmosphere to give it an intense blue colour.

It has a magnetic field and has at least eight moons.
