HEY STAR FRIENDS -- TRACE HERE. THE
BRIGHT GAS GIANT JUPITER HAS BEEN

SHINING FOR THE LAST FEW MONTHS, BUT IT S
BEEN IN RETROGRADE, THAT ENDS THIS WEEK!

FIRST WE NEED TO FIND JUPITER,
SO HIT THE SKIES ANY-TIME

AT OR AFTER SUNSET AND LOOK SOUTH.
YOU LL SEE A VERY BRIGHT SPOT.

RETROGRADE MOTION IS AN ILLUSION. ALL PLANETS
IN OUR SYSTEM GO IN THE SAME DIRECTION AROUND

THE SUN, AND NONE ACTUALLY CHANGE DIRECTIONS,
BUT THEY DO APPEAR TO CHANGE BECAUSE OF OUR

RELA-TIVE ORBITAL SPEEDS. JUPITER APPEARS
TO GO RETRO-GRADE FOR ABOUT 120 DAYS A YEAR.

IT S LIKE PASSING A SLOWER CAR ON A
RACETRACK. IF YOU RE GOING FASTER,

THE OTHER CAR COMES CLOSER, THAN APPEARS
TO REVERSE DIRECTION. ORBITS ARE SIM-ILAR!

WATCH A PLANET EVERY NIGHT AND IF IT APPEARS TO
MOVE WEST, IT S IN RETROGRADE MOTION. NOTHING

BAD WILL HAPPEN TO YOU BECAUSE OF THIS, BUT
YOU MIGHT LEARN SOMETHING! KEEP LOOKIN UP!
