How old are you the last time you learned about the solar system? Well, for our case, that might be years ago! But did you know that there might be some facts that you missed? Like how Jupiter has around 69 moons, or how the sunset in Mars appears blue? Behold, we have compiled 5 unique facts about the planets you might not know – let's jump in!

A day on Venus is longer than a Venus year.

Venus spins very slowly — one spin takes 243 days! Meanwhile, it only needs around 225 to revolve around the sun. Moreover, it spins from east to west! That means the sun rises from the west on Venus.

Uranus is lying on its side.

Uranus’s spin axis lies 98° off of its orbital plane with the Sun. No other planet is tilted more than 30° off its axis. Astronomers aren’t sure why!

Pluto is smaller than Australia.

Maybe that’s why pluto is now called a dwarf planet. Australia is about 4,000 km wide. It’s almost twice the size of the diameter of Pluto, which is only 2,370 km!

Earth is rotating slower each time.

Earth’s days are getting 17 milliseconds longer every 100 years. It might take really really long, but scientists predict that 140 million years from now, a day would be 25 hours.

Jupiter’s Red Spot is a giant hurricane.

The Great Red Spot, a feature on Jupiter’s surface which looks like a ketchup smudge, is actually a big hurricane that has lasted hundreds of years.
