Why does Mars seem to chase Jupiter?
All the planets travel around the Sun, like runners on a round track. Each planet has its own lane. Planets near the Sun have short lanes and zoom fast. Planets far away have long lanes and go slowly.
No! Jupiter is much, much farther away than Mars. From Earth, the two just look lined up.
Close one eye. Hold up one finger and line it up with a door across the room. Your finger is close and the door is far, yet they look together! That is what Mars and Jupiter are doing.
Mars is red because its dust is rusty, like an old iron nail. It has the tallest volcano we know, Olympus Mons, more than twice as tall as Mount Everest. Mars has two tiny moons.
About 1,300 Earths could fit inside Jupiter! It is made mostly of gas, so there is no ground to stand on. Its Great Red Spot is a storm bigger than Earth.
