What is the volume and density of Mars?

What is the volume and density of Mars?

It consists mostly (96%) of carbon dioxide, about 2% argon, 2% nitrogen and some traces of oxygen and water. It is also dusty. Mars's radius is 3 390 km (about half of Earth's) but it's mass is only 11% of Earth's mass. The average density of Mars is 3.9 g/cm3.

How large is Mars compared to Earth?

Mars (diameter 6790 kilometers) is only slightly more than half the size of Earth (diameter 12750 kilometers). Note the difference in color between the two planets. Almost 70% of Earth's surface is covered by liquid water. In contrast, Mars now has no liquid water on its surface and is covered with bare rock and dust.

What is Mars density?

3,93 g/cm³ Mars/Densité

What is the volume of Mars atmosphere?

Mars's atmosphere weighs 25,000,000,000,000,000 kg as compared to Earth's atmosphere at 5,148,000,000,000,000,000 kg. Which means Mars atmosphere is 1/206th that of Earth's. The volume is best expressed as scale height where Mars is 11.1 km vs. Earth 8.5 km.

How many Earths can fit into Mars?

Similarly, Earth's volume is a hefty 1.083 km3, which works out 1,083 billion cubic kilometers. By comparison, Mars has a volume of 1.63 km3 (163 billion cubic kilometers) which is the equivalent of 0.151 Earths.

Why is Mars less dense?

Density of Mars: The planet's overall density is lower than that of Earth's, estimated at 3.933 g/cm³, and this density increases the closer one gets to the core. Like Earth, this is due to the fact that the core is composed of iron and nickel, while the mantle is made up of silicate materials.

How does Mars compared to Earth in volume and density?

However, Earth's density is higher than that of Mars – 5.514 g/cm3 compared to 3.93 g/cm3 (or 0.71 Earths) – which indicates that Mars' core region contains more lighter elements than Earth's.

How is Mars surface?

Its surface is rocky, with canyons, volcanoes, dry lake beds and craters all over it. Red dust covers most of its surface. Mars has clouds and wind just like Earth. Sometimes the wind blows the red dust into a dust storm.

What is Mars' volume compared to Earth?
