no, Mars does not have a red spot or rings however Jupiter, the largest plant, does have a red spot called the 'Great Red Spot' and it also has a thin ring around it.
Yes it does my good fellow peep
Are you sure you don't mean Jupiter's red spot ?... The big red spot on Jupiter is believed to be a huge anti-cyclonic storm - that's been going since its discovery in 1831 !
The Big Red Spot is a particular feature of Jupiter, not Mars. It's an atmospheric storm that has raged for centuries, although at times it disappears from view for long periods. The largest feature on Mars is Olympus Mons - the largest known volcano in the Solar System. However, since the whole planet is largely red, calling this a 'Red Spot' is a misnomer.
