Day and night on Mars

Mars has day and night. It has this because it spins on its axis when it revolves around the sun. When half of Mars faces the sun, it is daytime and that is when it gets the most concentrated and direct rays of sun. When the other half of Mars is facing away from the sun, it is nighttime and doesn't get the direct rays of the sun. A day on Mars is 24 hours and 40 minutes long.

Years on Mars

Mars rotates on its axis, and it also revolves around the sun. Mars has years. 1 year on mars is 686.971 days long. A year is when Mars makes a full revolution around the sun. There is a type of gravity called centripetal force. Centripetal force is when the planet wants to pull away from the sun, but the sun's gravity is so strong it keeps the planet in our solar system and causes it to revolve around the sun. It takes Earth 24 hours to make a full revolution around the sun, so it takes Mars almost twice as long to make this revolution.

Seasons on Mars

Mars has seasons because it has a 25 degree tilt on its axis, and it revolves around the sun. The season are much colder on Mars then they are on earth, because Mars is farther away from the sun. The seasons are longer because Mars has a longer revolution time. Mars has multiple seasons similar Earth.

Phases of the moons on Mars

Mars has two moons. One is called Phobos, and the other is called Deimos. Both moons revolve around Mars and have tilts on their axis. The axis tilts are slight. The axis degree tilt for Phobos is 1.075, and the axis degree tilt for Deimos is 1.788. They revolve around Mars at different times and speeds. Phobos revolves around Mars every 7.39 hours, and Deimos revolves around Mars every 30 hours. Since Mars revolves around the sun, you will be able to see different phases of the moons at different times because there are two moons. The light from the sun will not be as strong compared to Earth.

Tides on Mars

Mars has no tides. The reason Mars does not have any tides is because there is little water, and all the water is frozen. If the water on Mars was not frozen, it would have tides because there are two moons. The reason there are tides on Earth is because our moon has a strong gravitational pull which pulls the water to cause tides. Since Mars has two moons, there would be stronger tides on Mars then there are on Earth.

Eclipses on Mars

Mars has eclipses because the two moons revolve around Mars, and Mars revolves around the sun. Mars's eclipses are very rare. They are rare because the moons revolve at different times. Eclipses occur when the moons fall behind Mar's shadow.

Summary

Mars and Earth have some similarities and some differences. Mars and Earth both have day and night. They have day and night because they both rotate on their axis. Mars takes longer to rotate on it’s axis. A day on Mars is 24 hours and 40 minutes. A day on Earth is 24 hours. Earth and Mars both get direct and indirect light from the sun. When Earth and Mars receive direct rays from the sun, it is daytime, and when they don't receive direct rays from the sun, it is nighttime. Earth and Mars both have years, but Mars’s year is much longer than Earth's. The year is longer because Mars is farther away from the sun. Mars’s year is 687 days, and a year on Earth is 365 days. Earth and Mars both have seasons due to their tilts on their axis. The seasons on Mars will be much colder than Earth, because Mars is a lot farther away from the sun than Earth is. When the planets revolve around the sun, their seasons change. Mars and Earth both have moons, and the moons have phases. There are more moon phases on Mars because Mars has 2 moons and Earth has 1 moon. The Earth has tides because it has water and a moon with a strong gravitational pull. Mars does not have tides because all of its water is frozen. If Mars were to have unfrozen water, there would be stronger tides than those on Earth because there are 2 moons. There are eclipses on Earth, but they are rare. The eclipses on Mars are even more rare because there is less tilt to the moon's axis.
