The Outer Planets

[Last Update: 03 August 2018]
These planets should not need to worry about global warming for quite some time! They are the six planets in our solar system farther from the sun than Earth. All images were taken from NASA spacecraft, including the recent remarkable shots from the New Horizons mission. Of course, now they say Pluto is not even a planet. Or maybe it is. Ho-hum.

Here is our neighbor as we move away from the sun: Mars.
We once thought there were canals on its surface. Thanks to many space missions, we know much more now, but mysteries still abound.

And the BIG BOSS of our solar system: Jupiter.
It has rings and LOTS of moons. Galileo discovered the four largest moons.

We used to think it was the only planet with rings: Saturn.
Talk about moons! Saturn now appears to be the king in that category.

However you pronounce it, it's mostly a big gas bag: Uranus.
More jokes have been made about this poor planet than any other!

A smaller, differently-colored gas bag: Neptune.
Cold, a long distance from us. And sometimes it is the ninth planet. If you count Pluto.

Finally, the tiniest and most distant: Pluto.
Is Pluto a planet or an asteroid? Pluto and its moon Charon (shown in the background of this image) have nearly the same mass, and therefore orbit each other around a point between them.
Sometimes Pluto is the eighth planet because its odd, very elliptical orbit crosses Neptune's orbit.
