I think that this one is pretty good.
"My Very Enthusiastic Mother Just Served Us Noodles", which stands for Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Another one is:
Mercury and Venus, Earth and Mars. Look at all the planets in amongst the stars. Jupiter and Saturn, Uranus too.
Hope this helped!
Please thank me and rate me a five star :)
