I use this sentence↓to help me remember my planets:
Martha
Visits
Every
Monday
and (asteroid belt)
Just
Stays
Until
Noon
Period
The first letter of every word represents a planet.
For example: the “M” in Martha is represents Mercury, the first planet. And the “E” in every stands for Earth.
But is the Pluto still a planet, due to the latest resarch ? 🙂
