PLANETS
“Well the Sun’s a hot star,
And Mercury’s hot too!
Saturn’s got those icy rings
And Uranus spins on its side!
Venus is the brightest planet,
And Earth’s home to me and

Neptune’s really windy,
And Pluto’s really small
Mars is the red one,
And Jupiter’s most wide
Well we wanted to name the
planets, and now we’ve
named them all!
