SEASONS25°23.5°

Seasons of two planet similar but since Mars year is aproximatelly twice as long.Therefore its seasons are longer too.Due to elliptical orbit of Mars ,some seasons are longer than other seasons.Northern hemisphere of Mars has longer spring and summer and Southern hemisphere of Mars has longer autumn and winter.

WEIGHT

Weight is a measure of gravity’s effect on mass.It is the mass multiply with specific gravity of the planet.Therefore it can be change for planet to planet.

If you weighed 100 kg on Earth ,you would weigh 38 kg on Mars.
