Facts About Mars and Its Orbit

without comments

Mars has fascinated people for as long as mankind has known about it. Scientists have studied its ability to orbit our solar system for centuries. They often compare the planet to Earth to understand their movement and evolution patterns. It is the second smallest planet in our solar system, yet it is probably the most well known one. The planet is a tenth of the size of Earth with a density of 3.933 grams/cubic centimeter. These characteristics provide an understanding of its existence in the universe. Experts suggest that Mars’s density is similar to Earth’s moon. To put this into perspective Mars is only 4/5 of Earth’s density.

Less mass suggests that Mars’s gravity is also less than Earth’s. This suggests that a person or object that is 100 pounds on Earth will likely weigh 38 pounds on Mars. It is important to know the difference between weight and mass to appreciate Mars’s physical characteristics. Gravity does not equate to size as Mercury has greater gravity, yet it is smaller than Mars. People often think that they will loose weight when they are in space; however, it will likely stay the same. They often feel lighter as they float in the air.

Scientists suggest that as Mars is further away from the sun its orbital period is longer than Earth’s. They calculate it as 687 Earth days. Experts claim that seasons are similar to our own except that they are twice as long. This suggests that Mars has a yearly cycle that we would understand. The whether conditions will likely change as the ‘Red Planet’ adapts as its movements increase. Mars’s gravitational force constantly changes at it orbits the solar system. This activity affects the other planets including Earth by decreasing the distance between Earth and Mars will likely decrease over the next 25 000 years. Mars will likely move more quickly as the distance between it and the other planets narrows. Its surface will likely change as its rotational patterns change.

The planet has two moons known which are considered to be asteroids. It is likely that they evolved over time until they were discovered. Scientists have never confirmed this theory; however, it is possible and should be used until proven otherwise. The moons continue to move towards the other planets as they also orbit the solar system.

Experts study and compare Mars’s ability to orbit our solar system with Earth’s. Mars has many known physical characteristics such as size, mass, density and gravitational pull. Mars is a tenth of the size of Earth while its moons are 4/5 the size of our planet’s. The moons are considered to be natural asteroids; however, this theory has not been confirmed. The planet’s orbital period is longer than Earth’s as it is further away from the sun. Its gravitational constantly changes as it orbits the solar system. In conclusion Mars will likely move more quickly as the distance between it and the other planets decreases. They will move towards the other planets as they orbit the solar system.
