I'm having a hard time remembering the order of planets in the solar system. Can you help me?

Sure, the order from the Sun outward is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.

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.
