All About Mars

Day and Night on Mars

Mars will have day and night because it's a planet that spins on its axis and has a sun. The amount of a day on Mars is 24 hours and 40 minutes. When Mars is facing the sun it is day time, stronger or concentrated light. When Mars is facing away from the sun, it is night time and weaker or delute light.

Years on Mars

Mars will have years because it revolves around the sun for 686.98 earth days. This is the time it takes Mars to make one full orbit around the sun on its 25 degree axis. Mars has a slow speed compared to us because Mars has more of a distance to travel than Earth.

Seasons on Mars

Mars will have seasons because the planet is revolving around the sun. The tilt of Mars is 25 degrees and without this tilt there wouldn't be seasons on Mars. Mars revolves around the sun slower than Earth does because of where it's positioned. Mars has summer, winter, spring and fall but these are longer seasons than ours because they have a longer year.

Tides on Mars

Mars doesn't have any tides because they don't have an ocean and the water is frozen. The moons gravitational force causes tides, but to be able to have tides you need a ocean for high and low tides during the day and Mars doesn't have this. If there was water on Mars there would be tides because it has a moon and a sun.

Phases of the Moon on Mars

Mars does have phases of the moon because it has a planet, moon and sun. Mars is on a tilt that causes Mars to rotate on its axis. As the moon goes around Mars you see the bright parts of the moon at different angles of where the moon is positioned during different days.

Eclipses on Mars

Mars would have eclipses because the moon revolves around Mars. Mars has two moons and eclipses will occur more often because Earth only has one moon. At some point the moon will line up between sun and Mars creating an eclipse. The two moons are small and can't create a full eclipses but part of one. Mars eclipses only last for 30 seconds because the moons are smaller than our moon on Earth. These eclipses happen when the moons enter Mars shadow or when the moon's shadow falls on Mars.

Summary

One major similarity is Mars and Earth both have a sun that we revolve around. We both also have at least one moon that revolves around us. Earth and Mars both have a tilt on its axis. We both have years because we both revolve around the sun but Earth's year is 365 days and Mars is 686.98 earth days. This happens because we both have a tilt but Mars tilt is 25 degrees and Earth's tilt is 23.5 degrees also Earth is closer to the sun than Mars. We both have seasons because we both revolve around the sun. One difference is we revolve around the sun faster than Mars does because we are closer to the sun. Another major difference is we have oceans and tides and Mars doesn't have tides because they don't have oceans. Earth is closer to the sun than Mars because of where it is positioned in the Solar system. Another major difference is we have life on Earth and Mars has no life.
