Mars, because it takes the longest to get from opposition to opposition, when accounting for Earth's path around the Sun/
Once round the Sun for Mars is 687 days. It takes 780 days (the synodic period) for the Earth to catch up Mars for the next opposition (i.e. the closest pass).
29.53 days is a synodic period. One Full Moon to the next.
Mars has an orbital period of around 687 days.
Mars.
686.980 earth days, sidereal period; 779.94 earth days, synodic period.
The synodic period of the moon is 29.5 days.

Yeah this is the Synodic Period... are you doing a crossword for a planet class right now... me too!

It's because we are going round the Sun and so are all the planets. For that reason the time it takes for a planet to go round the ecliptic and arrive back at the same apparent position - called its synodic period - is longer than a year. Venus and Mars have the longest synodic period because their times to go round once are the closest to 365 days. They take 225 and 687 days to go round but the synodic periods are 584 and 780 days. On the other hand the far-out planets do not move much in a year. Neptune takes 165 years to go round so its synodic period is only a little over 365 days and is 367½ days.
The sun has two types of period of rotation, the sidereal rotation period and the synodic rotation period. The sidereal rotation period is 24.47 days. The synodic rotation period is 26.24 days.
The synodic period of the moon is about 29.53 days.
a period on mars is why the colour of the ball it is red
A sidereal year is measured based on the planet's position in space relative to the background stars. A synodic year is measured based on the planet's position relative to the star it rotates around (i.e. the sun) Here's an image that is pretty helpful in visualizing.
Mars has a rotational period of 24.6 hours.
