Comparing mars and earth

At this distance, Phobos Comparing mars and earth below synchronous altitude, which means that it takes only 7 hours to orbit Mars and is gradually getting closer to the planet.

Earth and Mars have their share of similarities, but also some rather stark differences. With a mean radius of km and a mass of 5. Both planets have a silicate mantle surrounding their cores and a surface crust of solid material.

Mars's axial tilt is very similar to Earth's, being inclined In terms of their orbits, Earth and Mars are also quite different. This means that one Martian day aka. Earth and Mars are similar when it comes to their basic makeups, given that they are both terrestrial planets.

Earth has a dense atmosphere composed of five main layers — the Troposphere, the Stratosphere, the Mesosphere, the Thermosphere, and the Exosphere. Wikipedia Commons Today, Mars has weak magnetic fields in various regions of the planet which appear to be the remnant of a magnetosphere.

Sizes, Masses and Orbits: Earth and Mars have also experienced many impacts from asteroids and meteors over the years. About 76 percent of it is nitrogen, with about 21 percent oxygen. At perihelion, when it is closest to the Sun, it orbits at a distance of approximatelymillion km 1.

With a mean radius of km and a mass of 5. This in turn is what caused Mars to lose the liquid water that existed on its surface, as the environment to become increasing cold, desiccated, and inhospitable.

The surface of Mars is dry, dusty, and covered in dirt that is rich iron oxide aka. Space Shuttle Endeavor silhouetted against the atmosphere.

This would seem to indicate that Mars had a magnetosphere in the past, and explanations vary as to how it lost it. However, in terms of their sidereal rotation time it takes for the planet to complete a single rotation on its axis Earth and Mars are again in the same boat.

In many ways, the study of Mars provides Earth-bound scientists with a control set as they look at the processes of climate change, geophysics, and the potential for life beyond our own planet. It's mean density is 3. Volcanic hazards Wrong place, wrong time. Some of these channels are quite large, reaching 2, kilometers in length and kilometers in width.

When it comes to magnetic fields, Earth and Mars are in stark contrast to each other. We now know that though Mars may currently be very cold, very dry, and very inhospitable, this wasn't always the case.

The field ranges in strength between approximately 25, and 65, nanoteslas nTor 0. The largest mountain discovered in the solar system so far lies on Mars, Comparing mars and earth 78,foot-tall Olympus Mons.

In addition, Earth has a mass that is 10 times greater. And possibly plenty of the liquid type long ago. Between the two planets, there are similarities in size, inclination, structure, composition, and even the presence of water on their surfaces.

Mars is quite similar, with a surface covered by mountain ranges, sandy plains, and even some of the largest sand dunes in the Solar System. However, in terms of their sidereal rotation time it takes for the planet to complete a single rotation on its axis Earth and Mars are again in the same boat.

Map from the Mars Global Surveyor of the current magnetic fields on Mars. Earth and Mars have also experienced many impacts from asteroids and meteors over the years.

Water Inundates the place, especially in basements and during picnics. Their histories are described by dramatic deliveries of molten material to the surface of each planet from their respective interiors.

All of these factors will have to be addressed if ever human beings want to live there. Earth and Mars have their share of similarities, but also some rather stark differences.Mars compared to Earth December 7, by Matt Williams, Universe Today At one time, astronomers believed the surface of Mars was crisscrossed by canal systems.

Earth is a living planet because it is habitable by living organisms. It has a perfect condition for life hence organisms exists not only on the land, but also in the water and the atmosphere.

Mars on the other hand does not have the correct atmosphere, and a temperature not conducive for life.4/4(5). Mars is the most Earth-like other world known, yet the two planets are really a world apart. Mars is the 4th planet from Sun, and the place that holds our imagination because of the possibility that there might be life there.

There are some similarities to Earth, like its day length. If it were on Earth, it would stretch across the USA. Gigantic Features of Mars Mars is a smaller planet than Earth, but it has some awesome gigantic features!
