I'm having a hard time remembering the order of planets in the solar system. Can you help me?
user
Sure, the order from the Sun outward is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.
assistant
Thanks. Is Pluto still a planet?
user
It is a planet, but it was reclassified as a dwarf planet when it was observed not to be spherical.  This is in the news today because there was a scientific debate about it, which was resolved by a vote of the International Astronomical Union (IAU).  Does this answer your question?
assistant
Yes, thanks.
user
You’re welcome. Can I help with anything else?
assistant
Is there a good way or method of memorizing the order of the planets?
user
I recommend drawing or writing them out, maybe on a wheel.  You might also try making it into a song, like “Mercury, Venus, Earth...”

There are many effective memory techniques.  For example, you can use mnemonics.  Mnemonics are memory tricks that exploit the connection between a thing (like a word or number) and a related thing (a picture, sound, or action) to aid in remembering.  If you want to remember the order of the planets, you could do something like this:

Mercury (sounds like “Mercury”) was the first planet.  Venus (sounds like “Venuses”) was the second.  Earth (sounds like “Earth”) was the third.  Mars (sounds like “Mars”) was the fourth.  Jupiter (sounds like “Jupiter”) was the fifth.  Saturn (sounds like “Saturn”) was the sixth.  Uranus (sounds like “Uranus”) was the seventh.  Neptune (sounds like “Neptune”) was the eighth.  Pluto (sounds like “Pluto”) was the ninth.

Does that help?
