What is the mass and diameter of Mars?
Its diameter, at 3,474.8 km, is one-fourth the diameter of Earth; and at 7.3477 × 1022 kg, its mass is 1.2% of the Earth’s mass. It’s mean density is 3.3464 g/cm3 , which is equivalent to roughly 0.6 that of Earth.

What is Mars radius and diameter?
2001 Mars Odyssey
| EARTH | MARS | |
|---|---|---|
| Average Distance from Sun | 93 million miles | 142 million miles |
| Average Speed in Orbiting Sun | 18.5 miles per second | 14.5 miles per second |
| Diameter | 7,926 miles | 4,220 miles |
| Tilt of Axis | 23.5 degrees | 25 degrees |
Is mass greater on Mars?
Since Mars has less mass than Earth, the surface gravity on Mars is less than the surface gravity on Earth. The surface gravity on Mars is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mars.

Why is the mass of Mars so low?
Models of our solar system’s formation suggest that Mars should be between 1.5 and two times Earth’s mass. Instead, it weighs in at a mere one-tenth the mass of our world.
Can you walk on Mars gravity?
Of course it’s possible to walk on Mars. Mars is mostly rock, and it has a gravitational pull, so as long as you’re suited up enough to protect you from the extreme temperatures, the high radiation, and the lack of oxygen, you’ll be able to walk around on Mars just fine.
What is the farthest Mars is from Earth?
The minimum distance from the Earth to Mars is about 54.6 million kilometers. The farthest apart they can be is about 401 million km.
Does Mars have a magnetosphere?
Countering the effects of space weather Mars doesn’t have an intrinsic global magnetic field, but the solar wind directly interacts with the atmosphere of Mars, leading to the formation of a magnetosphere from magnetic field tubes.
Is Mars older than Earth?
“Mars is believed to be geologically older than Earth, yet [both] formed out of the same material very close to each other,” Matthew Clement, the paper’s lead author and a graduate researcher in planetary science at the University of Oklahoma, told me.
