Planets is the STEM song from the episode Robots in Space. It is sung by Blaze and AJ and plays after the Monster Machines escape the collapsing wormhole. This is the only other STEM concept taught after coding in the other Robot Riders episodes.
Blaze, AJ: Planets are spinning round and round
Orbiting around the sun
(Whoa-oa, whoa-oa, whoa-oa-oa-oa)
Blaze: Mercury's fast, and Venus is hot
Earth's the one that's full of life
(Whoa-oa, whoa-oa, whoa-oa-oa-oa) AJ: Mars is red, Jupiter's biggest
And Saturn's got rings made of ice
(Whoa-oa, whoa-oa, whoa-oa-oa-oa)
Blaze, AJ: Uranus, Neptune are big gas balls
The dwarf planet Pluto is really small
Planets are spinning round and round
Orbiting around
Orbiting around the sun
