A simplified demonstration of how planets move:

The planets orbit the sun in ellipses on a relatively flat plane

The sun is moving through space around a massive black hole in the middle of our galaxy, the Milky Way. This is the second part of the .gif, when the planets start spiraling.

The Milky Way is part of a cluster of galaxies called the Local Group, which orbit around a center between us and the Andromeda Galaxy.

And the Local Group is part of the Virgo Supercluster, which is one of millions to billions of superclusters in the observable universe.

Not to mention all of that is speeding “outward” as the universe expands. Probably. At speeds approaching light-speed. 

But despite all of this movement, we are able to shoot a rover attached to a lowering crane and hit a designated landing spot on one little planet. 

If that isn’t an awesome example of science, I don’t know what is.
