Question

The student recorded the actual sizes of the Sun and planets.

Answer 1

• Mercury. 4,878 km. 0.5 mm. 0.38.

• Venus. 12,104 km. 1.2 mm. 0.95.

• Earth. 12,756 km. 1.3 mm. ...

• Mars. 6,794 km. 0.7 mm. 0.53.

• Saturn. 120,660 km. 12.1 mm. ...

• Uranus. 51,118 km. 5.1 mm. ...

• Pluto. 2,300 km. .23 mm. 0.18.

Pluto isn't sentient; it doesn't mind its new dwarf planet status. What is the mnemonic device to remember the planets? My very eager mother just served us nine pizzas -- the planets, in order, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
