Where science and tech meet creativity.

The Solar SystemIn Astronomy we have two terrible patterns of words to try and remember. One is the order of the planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune (image left, credit: NASA). The other is the spectral types of stars: O, B, A, F, G, K, M. For both these patterns we have unsatisfying mnemonics. This week I am assigning my students to please come up with a new one for spectral types (and they can submit them in the comments here as well as in their HW if they want to share).

As well as getting their ideas, I thought I’d ask what you, my often silent non-student readers, think are useful ways to remember the planets and stars. So, in the comments, give me a sentence to remember you and the stars and planets by!

What do I use?
For planets (M V E M J S U N): My very evil mother just served us nothing.
For stars (O B A F G K M): Oh, be a frightening Godzilla. Kill Mothra!

What do you use?
